Students, you must have all crossed the suspension bridge! No, on this cloudless day, my classmates and I will also embody this "masterpiece" of fear.
Arrive at the suspension bridge in Quanshan Park. We started to cross the suspension bridge, and my curiosity drove me to walk forward bravely. Some of the students beside the suspension bridge were eager to try, while others were timid and stepped back. I craned my neck to take a look, and couldn't help but shudder in my heart. There is a suspension bridge made of wood more than ten meters above the river. This suspension bridge is less than half a meter wide. There are neither handrails nor railings on the side. The swaying bridge hanging in mid-air is surrounded by the rushing river water. I was frightened to see it. I hesitated: Go up or not? Looking back, I saw that the bridge was crowded with classmates and there was no way to retreat. I plucked up the courage and thought: Crossing the suspension bridge is such a rare experience, but isn’t it a waste of time? In this way, I carefully stepped onto the swaying suspension bridge. With my hands stretched out flat and my feet stepping on the somewhat loose wooden boards, I took the first trembling step. The suspension bridge was shaking "creakingly", but it seemed to be worse than I imagined it was smooth, so I quickly quickened my pace and was almost in the middle. Just when I was secretly happy, suddenly, my foot tripped and the suspension bridge shook violently. I glanced at the river surface with my eyes. , I felt like I was hanging in mid-air, what if..., I closed my eyes, not daring to continue thinking, my legs were weak, and I was so scared that tears were about to flow out. At this moment, the encouragement from my classmates came to my ears: "Xiaolan, don't look down, raise your head and walk forward. Believe in yourself, you will get through it!" My heart seemed to calm down all of a sudden, and I raised my head. , held my chest high, stood firm step by step, and walked forward steadily. Finally, I won and reached the other side.

Just after the Spring Festival last year, my parents and I went to Jinfo Mountain for a trip. On the way, I walked across the suspension bridge by myself for the first time.
That afternoon, the weather was fine, and we took a bus to the first stop of Jinfo Mountain - Wolongtan. Surrounded by mountains, shaded by green trees, gurgling water, the scenery is very beautiful. It is indeed a famous scenic spot in the country! A group of us walked on the plank road in the scenic spot and were intoxicated by the picturesque scenery. From time to time, crisp bird calls can be heard in the distance. In the middle of the river not far away, there are a few monkeys playing. They must be playing the game of "fishing for the moon in the water". It is still daytime.
At this moment, we finished walking the plank road. Suddenly, someone shouted: "Look, the suspension bridge!" I looked up and saw that the road ahead was in an S shape. Across the river, there were more than a dozen wooden bridges more than ten meters above the river. A suspension bridge made of iron ropes! Under the bridge is the rapid river water and pebbles of different sizes. Someone walked onto the bridge, and the way they were swaying made me feel frightened and uneasy. I thought to myself: "This time, my father should carry me across the bridge, right? I don't dare to cross it myself." At this time, my mother said: "Son, we are about to cross the suspension bridge, please be careful."
"Click", my heartbeat quickly accelerated with my mother's voice. I retreated in my heart and looked at my dad timidly, hoping that my dad could help me. Dad may have seen what I was thinking, so he knelt down and said softly to me: "Son, you have grown up and are a little man. I believe you will be able to pass. In this way, mom will pass in front, you in the middle, dad Can you protect me from behind?" I nodded and decided to try it myself. Besides, there was a child in front of me who was younger than me and he passed by himself. How could I have the nerve to let my father carry him there?
In this way, with the encouragement of my parents, I carefully walked onto the swinging suspension bridge. I grasped the iron cables of the suspension bridge tightly with both hands, stepped on the loose wooden boards with my feet, and took the first step forward with a trembling body.
"Very good! Son, walk slowly and look forward!" Dad reminded me from behind. I saw my mother looking at me with approval on the other side of the bridge and smiling at me. My heart suddenly became much calmer, and my pace became faster. Just when I was secretly happy, suddenly something shook my feet, and I stumbled forward involuntarily, almost falling. But at this moment, the suspension bridge began to sway violently, and a wooden board on the bridge almost fell off. I glanced at the river with my eyes and felt as if I was suspended in mid-air. If I was shaken into the river----, I closed my eyes and did not dare to continue thinking. I couldn't help but feel panicked, my legs felt weak, and I was so scared that tears almost flowed out. "Son, hold on tight, don't look down. You know, you are great, you will pass soon." Just when I was about to give up, my father cheered me up from behind. I suddenly thought of the TV series "The Long March" I watched not long ago, the scene of the Red Army crossing the Dadu River. There were not even wooden boards on the chain bridge, and the Dadu River was even more turbulent under the bridge. However, the Red Army was not afraid of hardships and bravely crossed the river. Thinking of this, thinking that my father was protecting me from behind, my heart calmed down again. I stood up straight, grabbed the iron rope, stepped on my feet step by step, and finally reached the other side. I breathed a sigh of relief, and my parents praised me for being brave. Next, I followed the same method and passed the next few suspension bridges relatively easily, and came to the highest point of Wolongtan - Songziyan.
I stood on the Songzi Rock, looking down at the suspension bridge like a coiled dragon at the bottom of the mountain, and I still felt a lingering fear in my heart. But when I saw the wonderful scenery on the top of the mountain, and the sunset shone on my face, which was still dripping with crystal beads of sweat, I said excitedly: "I finally walked across the suspension bridge myself, it's great!"
Hope to adopt 3. Suspension bridge composition
The suspension bridge is composed of two pavilions, some wooden boards and iron chains. There are colorful lights winding on the iron chains, which is very beautiful.
At night, the lights on the suspension bridge light up one after another. From a distance, it looks like a paradise of stars. Whenever night falls, I will go to the suspension bridge to play.
After passing the first pavilion, you will come to the beautiful suspension bridge, and you will be swaying when you walk on it, as if you are drunk. Slowly I walked to the second pavilion. The structure of the first pavilion and the second pavilion were similar, just like a pair of twins.
The suspension bridge leads to a small island. The scenery on the small island is beautiful, with trees and grass growing on it. I sat in the pavilion. The pavilion and chairs were made of stone. It was cold and comfortable to sit on.
I looked at my watch and saw that it was already very late. I stood up and walked back. Walking on the suspension bridge is like swinging on a swing. I can't forget the fun it brings to me.
I got off the suspension bridge, looked at the magnificent suspension bridge, and reluctantly went home. 4. An essay of more than a thousand words introducing the function of a suspension bridge
Suspension bridge A suspension bridge refers to a superstructure that uses cables (or steel chains) suspended through cable towers and anchored on both sides of the bank (or both ends of the bridge). The main load-bearing component of the bridge.
The cable geometry is determined by the balance conditions of forces and is generally close to a parabola. Many suspenders hang from the cables to suspend the bridge deck. Stiffening beams are often installed between the bridge deck and the suspenders to form a combined system with the cables to reduce deflection deformation caused by live loads.
The history of suspension bridges is ancient. Early tropical primitive people used rattan, bamboo, and tree stems in the forest to make suspension bridges to cross streams. The suspension cables used were vertical, cable-stayed, or a mixture of the two.
The original rattan and bamboo bridges in Borneo, Laos, and Java are all the prototypes of early suspension bridges. However, the earliest prototype of a suspension bridge with written records belongs to China, and to this day, it is still influencing the development of suspension bridge forms in the world.
As far back as the third century BC, the "箮" (bamboo cable bridge) was built in Sichuan, China. Qin captured Western Shu, Sichuan's "Yanyuan County Chronicle" records: "In the 30th year of King Nan of Zhou (285 BC), Qin set up Shu as a guard and firmly captured the 箮, which first appeared in books.
By the time Li Bing was Shou (256-251 B.C.) built seven bridges. Among the seven bridges, there is a Zuo bridge, which is a bamboo cable bridge.
It can be seen that bamboo cable bridges have been recorded in my country at least in the third century BC.
As early as 50 BC (the fourth year of Ganlu reign of Emperor Xuan of the Han Dynasty), a hundred-meter-long iron cable bridge had been built in Sichuan. In 1665, Xu Xiake wrote a travelogue entitled "Tie Cable Bridge", which was translated to the West by missionary Martini. The book recorded in detail an iron cable bridge with a span of about 122m in Guizhou in 1629.
In 1667, after the French missionary Kircher returned from China, he wrote "China's Miracles", which recorded the Lanjin Iron Cable Bridge in Yunnan in 65 AD. The book has been translated into many languages ??and reprinted many times.
According to research by historians of science and technology, it was only after the publication of the above-mentioned book that the rope bridge was spread to the West. It can be seen that the suspension bridge in ancient China was an original invention and a leading one.
The famous Luding Bridge consisting of nine iron chains on the Dadu River in Sichuan was built in 1706. Suspension bridges also appeared earlier in Yunnan. According to "Xu Xiake's Travels·Yunnan Travel Diary", the Tengqiao Bridge on the Dongjiang River in Longchuan, Yunnan says: "The source of the Dongjiang River in Longchuan flows to the south.
The vines are tied to the bridge. From above to cross..."The development of suspension bridges in modern China. Since 1938, a highway suspension bridge was built in Hunan, which can carry 10 tons of cars. Subsequently, a number of highway suspension bridges were built. After the founding of the People's Republic of China, more than 70 such bridges were built in Japan. However, the spans are small, the width is narrow, the load standards are low, and the development lags behind.
After the 1990s, China's suspension bridges opened a new historical chapter. The Guangdong Shantou Bay Bridge with a main span of 452m is known as China's first large-span modern suspension bridge, and its main span ranks first in the world among prestressed concrete reinforced suspension bridges; the Xiling Yangtze River Bridge, with a main span of 900m, is the first independently designed in China Fully welded steel box stiffened girder suspension bridge; Jiangsu Jiangyin Yangtze River Bridge, a steel box stiffened suspension bridge with a main span of 1385m, ranked as the fifth largest span suspension bridge in the world; Jiangsu Runyang Yangtze River Highway Bridge South Branch Bridge completed in 2005, with a main span With a main span of 1,490m, it is the third longest-span suspension bridge in the world; the recently completed Zhoushan Xihoumen Cross-sea Bridge has a main span of 1,650m, ranking second in the world.
It can be seen that our country has entered the world's advanced ranks. Aizhai Extra Large Suspension Bridge is located in Aizhai Town, Xiangxi, Hunan.
The Aizhai Suspension Bridge is about 20 kilometers away from Jishou City. It spans the valley near Aizhai Town. The Dehang River flows through the valley bottom. The design elevation difference between the bridge deck and the ground is about 330 meters. The bridge type plan is a single-span suspension bridge with steel truss stiffened beams, with a total length of 1073.65m, and the main span of the suspension bridge is 1176m.
The bridge spans the Aizhai Grand Canyon, with the main span ranking third in the world and first in Asia. The construction of modern suspension bridges in my country began in the 1860s. Some semi-stiffened single-chain and double-chain suspension bridges with a span of less than 200 meters were built in the southwestern mountainous areas. The more famous ones are the Chongqing Chaoyang Bridge built in 1969; The completed Dazi Bridge in Tibet has a span of 500 meters.
Transportation construction in the 1990s *** finally ushered in a new era of building modern long-span suspension bridges. The Guangdong Shantou Bay Bridge with a span of 452 meters uses concrete stiffened beams; the Guangdong Humen Bridge is a steel box girder suspension bridge with a span of 888 meters; the Jiangyin Yangtze River Bridge with a main span of more than 1,200 meters is under design.
The simultaneous construction of three suspension bridges will enable my country's bridge science and technology to quickly catch up with the world's advanced level. 5. Essay on the cable bridge in my hometown
My hometown is a beautiful small town with mountains on one side and water on three sides.
A clear and winding Yujiang River flows slowly eastward through the small town. At the end of the south gate of the small town, a Xujiang Cable Bridge is like a rainbow lying on waves, spanning the west bank of the Xujiang River.
Before entering the cable bridge, you can see the four characters "Xujiang Cable Bridge" shining brightly in the bright sunshine. The entire bridge, which is composed of steel bars and cement, is held firmly by several thick and long iron cables.
It is more than 400 meters long and 11 meters wide. There are also wooden walkways on the left and right sides to reduce the weight of the bridge.
To get on the bridge, you have to go up a long slope-like approach bridge to the right side of the main approach bridge. There is a black stone tablet that records the construction information of the bridge.
During the day, the bridge is bustling with traffic and crowds of people. City people cross the bridge to go to the countryside to relax and enjoy the scenery of the fields.
Farmers cross the bridge into the city to sell vegetables and fruits. Everyone's face was beaming with joy.
On a summer evening, there is a cool breeze on the bridge, and the neon lights twinkle and complement the bright stars in the sky. Beautiful singing, cheerful laughter, and the sound of running water combine to create a piece of heaven on earth. 6. Mitan Yellow River Suspension Bridge Essay about suspension bridges
Most bridges nowadays are made of reinforced concrete, with a strong flavor of modern craftsmanship, and wooden bridges are rare. If I see it by chance, it's just for appreciation. But in Guizhou villages in mountainous areas, there are still some suspension bridges that are still in use today.
The suspension bridge in this mountainous area is not supported by steel cables like in the scenic spot. It is very reliable in terms of safety and artistry. Most of these suspension bridges are about five to twenty meters long. They are usually erected between the mountainsides of two mountains, and their height is the same as the height of the mountainside. Hemp ropes are tied to wooden stakes at both ends. A suspension bridge usually has two to five hemp ropes, and at least two. Most of the bridges are paved with wooden planks, ranging from fully paved to half a meter apart, which is not very safe. The suspension bridge with the largest interval between wooden planks is nearly one meter, and is closed to children. Even small adults cannot cross it with one foot. It is the most dangerous suspension bridge. Except for single-plank bridges, suspension wooden bridges are the oldest bridges in the history of Chinese bridges, which can be seen from the rudimentary equipment and technology. 7.

Just after the Spring Festival last year, my parents and I went to Jinfo Mountain for a trip. On the way, I walked across the suspension bridge by myself for the first time.
That afternoon, the weather was fine, and we took a bus to the first stop of Jinfo Mountain - Wolongtan. Surrounded by mountains, shaded by green trees, gurgling water, the scenery is very beautiful. It is indeed a famous scenic spot in the country! A group of us walked on the plank road in the scenic spot and were intoxicated by the picturesque scenery. From time to time, crisp bird calls can be heard in the distance. In the middle of the river not far away, there are a few monkeys playing. They must be playing the game of "fishing for the moon in the water". It is still daytime.
At this moment, we finished walking the plank road. Suddenly, someone shouted: "Look, the suspension bridge!" I looked up and saw that the road ahead was in an S shape. Across the river, there were more than a dozen wooden bridges more than ten meters above the river. A suspension bridge made of iron ropes! Under the bridge is the rapid river water and pebbles of different sizes. Someone walked onto the bridge, and the way they were swaying made me feel frightened and uneasy. I thought to myself: "This time, my father should carry me across the bridge, right? I don't dare to cross it myself." At this time, my mother said: "Son, we are about to cross the suspension bridge, please be careful."
"Click", my heartbeat quickly accelerated with my mother's voice. I retreated in my heart and looked at my dad timidly, hoping that my dad could help me. Dad may have seen what I was thinking, so he knelt down and said softly to me: "Son, you have grown up and are a little man. I believe you will be able to pass. In this way, mom will pass in front, you in the middle, dad Can you protect me from behind?" I nodded and decided to try it myself. Besides, there was a child in front of me who was younger than me and he passed by himself. How could I have the nerve to let my father carry him there?
In this way, with the encouragement of my parents, I carefully walked onto the swinging suspension bridge. I grasped the iron cables of the suspension bridge tightly with both hands, stepped on the loose wooden boards with my feet, and took the first step forward with a trembling body. "Very good! Son, walk slowly and look forward!" Dad reminded me from behind. I saw my mother looking at me with approval on the other side of the bridge and smiling at me. My heart suddenly became much calmer, and my pace became faster. Just when I was secretly happy, suddenly something shook my feet, and I stumbled forward involuntarily, almost falling. But at this moment, the suspension bridge began to sway violently, and a wooden board on the bridge almost fell off. I glanced at the river with my eyes and felt as if I was suspended in mid-air. If I was shaken into the river----, I closed my eyes and did not dare to continue thinking. I couldn't help but feel panicked, my legs felt weak, and I was so scared that tears almost flowed out. "Son, hold on tight, don't look down. You know, you are great, you will pass soon." Just when I was about to give up, my father cheered me up from behind. I suddenly thought of the TV series "The Long March" I watched not long ago, the scene of the Red Army crossing the Dadu River. There were not even wooden boards on the chain bridge, and the Dadu River was even more turbulent under the bridge. However, the Red Army was not afraid of hardships and bravely crossed the river. Thinking of this, thinking that my father was protecting me from behind, my heart calmed down again. I stood up straight, grabbed the iron rope, stepped on my feet step by step, and finally reached the other side. I breathed a sigh of relief, and my parents praised me for being brave. Next, I followed the same method and passed the next few suspension bridges relatively easily, and came to the highest point of Wolongtan - Songziyan.
