The Three Gorges Dam is located in Sandouping Town, Yichang City, Hubei Province, China, 38 kilometers away from the downstream Gezhouba Water Control Project. It is the main project of the Three Gorges Hydropower Station, the core landscape of the Three Gorges Dam tourist area, and the eastern end of the Three Gorges Reservoir. It is the largest hydropower project in the world today.
The Three Gorges Dam Project consists of the main building and diversion works, with a total length of about 3,335 m and a crest elevation of 1.85m, with a total investment of 95.46 billion yuan. 65,438+0,994,65,438+2,004 officially started construction, and the whole line was completed on May 20, 2006. The power generation of the Three Gorges Hydropower Station in 20 18 exceeded 1000 billion kWh, setting a new world record for the annual power generation of a single power station.

20 19 A remark about "The Three Gorges Dam has been deformed and the dam is about to burst" has attracted attention on social media. The Three Gorges Group responded that the monitoring data since the operation of the Three Gorges Project showed that the building was in normal working condition and the project was safe and reliable.
The Three Gorges Project is the largest water conservancy project in the world, including dams, hydropower stations, navigation structure, the Mao Ping River protection dam on the right bank and underground power stations. The Three Gorges Dam is a concrete gravity dam with a crest elevation of1.85m, a maximum dam height of 1.8 1.0m, and a total dam axis of 2309.5m. The bedrock is pre-Sinian flash cloud plagiogranite.
As one of the eight technical designs of the Three Gorges Project, the safety monitoring of the Three Gorges Project has been comprehensively and deeply designed in the early stage, and a large number of safety monitoring facilities with complete categories have been set up.
Safety monitoring projects are divided into three categories: routine monitoring projects, special monitoring projects and geological environment monitoring projects, totaling 14. In addition, there are various patrol inspection items, forming a complete monitoring system covering all buildings and areas.
The embedding and observation of monitoring instruments started from 1994 and were implemented simultaneously with the main project. There were 12087 measuring points for embedding instruments. Among them, the number of deformation monitoring points is 268 1, and the intact rate is 99.8%.
