After more than five years of hard work, on July 1, 2006, the Qinghai-Tibet Railway will realize the opening of the whole line for trial operation, and the dreams of several generations will be lifted up by the solid railroad tracks. As the world's highest railroad, the opening of the Qinghai-Tibet Railway will completely end the history of the Tibet Autonomous Region, which accounts for one-eighth of the country's land area and has no access to railroads.
As early as the beginning of the last century, Mr. Sun Yat-sen put forward the idea of building a railroad to Lhasa, but in the old China of poverty and weakness, the best idea can only be written on paper, can not be put into practice. After the founding of the People's Republic of China, the builders of the new China took only 7 months and 4 days to build the first highway across the Tibetan Plateau into Tibet --- the Qinghai-Tibet Highway, and then the construction of the Tibet Railway was included in the important agenda of the Party Central Committee and the State Council. Under the care of Mao Zedong, Deng Xiaoping and other senior central leaders, the 814-kilometer-long Qinghai-Tibet Railway Phase I project from Xining to Golmud was paved in 1979, and was put into operation in 1984. However, limited to the country's economic strength and plateau permafrost and other road construction technical difficulties have not yet been resolved, the Qinghai-Tibet Railway Golmud-Lhasa section was forced to stop construction.
With the enhancement of China's comprehensive national strength, with the implementation of the western development strategy, in 2001, the Qinghai-Tibet Railway Gera section started construction, 100,000 construction troops from the four corners of the motherland to the Tibetan Plateau, so that the ancient plateau, vast snowy areas sprouted out of a thousand years of vitality and vitality, in this magical land has left countless songs of touching stories. Challenging the limit and creating the first-class", they interpreted the spirit of Qinghai-Tibet Railway with wisdom, sweat and hard work, and overcame the world-wide engineering and technical problems such as perennial permafrost, alpine cold and lack of oxygen, and ecological fragility, and broke the prediction of the western media that "the Qinghai-Tibet Railway can't even pass the wind and volcano", and created the "Qinghai-Tibet Railway", which is the first railway in the world. The Qinghai-Tibet Railway has broken the prophecy of the western media that "the Qinghai-Tibet Railway can't cross the wind and volcano at all", and has created world miracles. The Qinghai-Tibet Railway spans the Kunlun Mountains, Tanggula Mountains, Nianqing Tanggula Mountains, crossing the Yangtze River, the Yellow River and other sources of the five major water systems, such as the Xueshui River, Tuo Tuo River, Tongtian River and other nine rivers, crossing the Gobi Desert, swamps and wetlands and snowy grasslands, like a steel dragon across the world's third pole, and will become the Tibetan Plateau iron and steel aorta.

Wind Volcano Tunnel, Kunlun Mountain Tunnel, Yangbajing No. 1 Tunnel, Tongtian River Special Bridge, Kaixinling Special Bridge, Yangtze River Special Bridge, Lhasa River Special Bridge, the first high bridge of the Qinghai-Tibet Railway ---- Three Forks of the River Bridge, the first long bridge of the Qinghai-Tibet Railway is the Qingshui River Special Bridge, and the first long bridge of the Qinghai-Tibet Railway is the Qingshui River Special Bridge. Bridge ...... Qinghai-Tibet Railway Golmud to Lhasa section is 1,142 kilometers long, through a series of plateau tunnels, erected 675 bridges, bridges, the total length of 159.88 kilometers, equivalent to every 7 kilometers of railroads in the 1 kilometer of bridges.
The Qinghai-Tibet Railway is the world's longest mileage through the permafrost plateau railroad, the railroad through years of continuous permafrost mileage of 550 kilometers, known as "the world museum of permafrost engineering". The Qinghai-Tibet Railway is the first large-scale and comprehensive model of comprehensively applying various engineering measures to solve the permafrost problem in the field of engineering construction in the permafrost area of the world. These new ideas and engineering technology innovation, marking the Qinghai-Tibet Railway many years of frozen soil engineering practice has been in the world's leading level.
In order to solve the problem of permafrost in the field of railroad construction on the plateau of the world, China's railroad research departments as early as in the early 1960s, organized scientific and technological forces in the Qinghai-Tibet Plateau at an altitude of more than 4,800 meters along the wind volcano, the establishment of a scientific research base for permafrost - wind volcano observation station. For more than 40 years, scientific researchers have persisted in observing and recording meteorological and permafrost changes, accumulating more than 12 million valuable data for the construction of the Qinghai-Tibet Railway. Through a series of advanced techniques, the builders of the Qinghai-Tibet Railway have not only ensured safe construction under low-oxygen and low-pressure conditions, but also successfully cracked the problem of plateau permafrost construction. The "wind-volcano permafrost tunnel construction technology" has won the first prize of 2004 Qinghai Provincial Scientific and Technological Progress and the second prize of 2005 National Scientific and Technological Progress.
After decades of persistent preparation and five years of construction practice, China's railroad builders have successively overcome more than 20 of the world's plateau permafrost construction problems. The maximum speed of the Qinghai-Tibet Railway, which will be opened soon, can reach 120 kilometers per hour, which is much higher than that of the tundra railroads in Russia and other countries, which is between 40 kilometers and 60 kilometers per hour.
Before the Qinghai-Tibet Railway began construction, the relevant state departments conducted a special study on the climate, environment, species and ecology of the Qinghai-Tibet Plateau. The environmental objectives of the Qinghai-Tibet Railway include: to ensure that the permafrost environment remains stable, the water quality of rivers and streams is not polluted, soil erosion protection is effective, the plateau vegetation is effectively protected, wild animals are free to migrate, and the landscapes along the railroad are not damaged. In order to protect the exceptionally fragile ecological environment of the Qinghai-Tibet Plateau, the environmental protection investment of the Qinghai-Tibet Railway amounted to 1.54 billion yuan, and the participating construction units took "protecting every blade of grass and every tree on the Qinghai-Tibet Plateau" as their own responsibility, and took environmental protection measures such as transplanting turf, man-made wetlands in alpine zones, and setting up migration corridors for wildlife, which broke the "destroy first, treat later" principle of China's past engineering construction. It breaks the old mode of "destruction before treatment" of engineering construction in China, tries and explores the new mode of environmental protection of major projects in China, and becomes a model of environmental protection in the history of China's transportation.
The Qinghai-Tibet Railway straddles the uninhabited areas of Coco Sicily and Tanggula Mountain, and in the area above 4000 meters above sea level, the harsh plateau climate environment seriously threatens the life, health and safety of the builders. The General Command of Qinghai-Tibet Railway Construction puts forward the idea of "survival first, then production", and each participating unit "protects first before the soldiers move". Three-level medical institutions have been established along the project route, with a hospital every 10 kilometers on average, and workers can be effectively treated within half an hour when they are sick. Construction of large-scale use of modern machinery and equipment, greatly reducing the labor intensity of workers. Here, the people-oriented thinking has been fully embodied, thus creating a miracle that no one in the construction unit died of plateau disease.
Three
With the opening of the Qinghai-Tibet Railway line trial operation, the flow of people, logistics, information flow will accelerate the modernization process of this piece of high continent, low-cost, large capacity, all-weather uninterrupted railroad transport, will further activate the inner vitality of the Tibetan Plateau, so that the ancient plateau is more open, more vibrant.
Qinghai Province, the potential value of mineral resources retained reserves of 17.2 trillion yuan, accounting for 13.6% of the potential value of mineral resources retained reserves, many domestic and foreign investors have long been optimistic about the market, optimistic about the rich resources here, but due to the constraints of the transportation conditions in Qinghai Province, the slow progress of resource development. With the construction of Qinghai-Tibet Railway, under the care and support of the CPC Central Committee, the State Council and relevant state ministries and commissions, the project of constructing additional second line of Lanzhou-Qingdao Railway and the emergency project of Xigue section of Qinghai-Tibet Railway have been started successively, and there is an important breakthrough in the construction of Qinghai Railway, marking that the capacity of the province's railroad transportation of both passengers and cargoes has been greatly improved, and it will greatly promote the economic and social development of Qinghai and accelerate the pace of Qinghai's resource conversion.
After the completion of the Qinghai-Tibet Railway, Tibet will be included in the nation's well-connected railroad network for the first time, solving the problem of long-distance transportation in Tibet's economic activities through railroad transportation, greatly enhancing the amount of goods in and out of Tibet, promoting the development of the tourism industry, transforming backward ideological concepts, creating conditions for the adjustment of industrial structure, and eliminating the "bottleneck" constraints on the transportation of Tibet's sustainable development. "
These are the most important constraints on Tibet's sustainable development, and they have created good infrastructure conditions for Tibet's sustainable development.
At the same time, with the opening of the Qinghai-Tibet Railway, will provide tourists with more convenient, inexpensive transportation conditions, a large number of tourists at home and abroad will set foot on the plateau, by car, full of Qinghai Lake, Treasure Beach, Namucuo, Atomic City, Ta'er Temple, the Kunlun Mountains, Tanggula Mountain and other highland lakes and wetlands, mountains and snowy plains scenic spots, rich and unique highland tourism and cultural resources will also be further excavation and development. This will lead to the development of the tertiary industry in the two provinces of Qinghai and Tibet.
The change of the transportation pattern of the roof of the world will profoundly affect the pattern of economic and social development of this region, under the great traction of "railroad economy", the industrial resources and cultural advantages of the Qinghai-Tibet Plateau will be further integrated, and the industrial cooperation and division of labor will be more clear under the allocation of market resources, which will ultimately lead to the formation of a Qinghai-Tibet Plateau economic region, becoming an important development pole in the process of western development.
"Heavenly road" think
The sound of the whistle into the plateau.
Once, Qinghai was far away. A "in that distant place", singing her beauty, but also interpreted her distance;
Now, Qinghai is very close. A "heavenly road" jumped Kunlun, this head is the roof of the world, that head is the coastal mainland.
The Qinghai-Tibetan line, through the sigh of a thousand years of history, through the ancient silence of the plateau, through the "tundra invincible" myth, through the eyes of the world's amazement ...... through the mountains and mountains, through the clouds and fog, the dragon rises! "The third pole", when the world is shocked by the difference!
Isn't it? Wind up Kunlun, income curtains in the heart, is the world's greatness across the plateau of the majestic magic;
Not? The tide of the West China Sea, fluttering into the bosom of the chest, is a universal celebration of the achievement of the dream of the heroic atmosphere.
Memory lingers, more than 1,800 days and nights, every moment is faced with the difficult twists and turns, facing the cold and lack of oxygen; every moment is life, perseverance of the limit of the challenge, courage, wisdom of the greatest consideration.
Moved to stay in the heart, 100,000 troops prima donna, in order to shoulder the national mission, unity and collaboration, the will of the people, holding the colorful practice when the sky dance, spilling blood to write the Spring and Autumn, casting the monument of the heavenly road pack up.
From the pursuit of a dream come true, from the blueprint into reality, because of the strength of our great motherland, because of the great era of innovation, because of the spirit of the great nation. When the whistle sounded in the thousands of miles of pasture, when the iron dragon whistling in the vast snowy area, as the children of China can not for the Qinghai-Tibet line --- this we created the miracle of mankind and feel proud? Can not witness the opening of the Qinghai-Tibet line --- this exciting moment and rejoice!
The Qinghai-Tibet line, leaping out of the plateau, see the red sun in the East, jumped up in a new height.
The Qinghai-Tibetan line, advancing forward, with the eight winds, and advancing in a new era.
