In which city of China is the Three Gorges Dam located?

The Three Gorges Dam is located in Yichang City, Hubei Province, China.

The Three Gorges Dam is located in Xilingxia reach of the main stream of the Yangtze River, at the eastern end of the Three Gorges Reservoir, with a controlled drainage area of about 6,543,800 square kilometers. It is located in the Three Gorges Dam tourist area of Sandouping Town, Yiling District, Yichang City, Hubei Province. Built in 1994, it integrates flood control, power generation, shipping and water resources utilization. It is the main project of the Three Gorges Hydropower Station, the core landscape of the Three Gorges Dam tourist area, and today.

The Three Gorges Dam is mainly composed of water retaining and flood discharging main dam, power generation building, navigation structure and other buildings. The dam body is a concrete gravity dam with a dam axis of 2309.47 meters and a total length of 2335 meters. Dam crest elevation 185m, maximum dam height181m; The normal water level is1.75m, with a total storage capacity of 39.3 billion cubic meters, of which the flood control storage capacity is 221.50 billion cubic meters; The total installed capacity of power generation is 22.5 million kilowatts, and the annual power generation exceeds 654.38+000 billion kWh.

The Three Gorges Dam can improve the navigation conditions of the Yangtze River, increase the annual one-way navigation capacity of the Yangtze River from 6.5438+million tons to 50 million tons, and reduce the transportation cost by 35%-37%. 20 15- 12, the Three Gorges Dam was selected as the 30 best new tourist attractions in the Three Gorges of the Yangtze River.

Social benefits of the Three Gorges Dam

The concrete volume of the Three Gorges Dam is 1665438+ 10,000 cubic meters, which is the gravity dam with the largest concrete volume, the largest overflow orifice and the largest discharge in the world.

The completion of the Three Gorges Dam means that the Three Gorges Project has begun to give full play to its flood control capacity, raising the flood control standard of Jingjiang reach of the Yangtze River from 10 to 100, effectively protecting tens of millions of people in the middle and lower reaches of the Yangtze River and millions of hectares of cultivated land from flood threats, and giving full play to the role of the Yangtze River as a "golden waterway".

The power generation benefit of the Three Gorges Project is considerable, which helps to alleviate the energy bottleneck in China and plays an important role in building the energy artery and optimizing the allocation of energy resources. During the Tenth Five-Year Plan period, China put forward the transmission plan of "transmitting electricity from west to east", and built three transmission channels: north, middle and south. Among them, the central passage starts from Sichuan in the west, crosses the Three Gorges and reaches Shanghai in the east.

With the construction of the power transmission and transformation project of the Three Gorges Dam, a series of power transmission projects such as No.3 Power Plant and No.3 Power Plant have been put into operation one after another, and the west-to-east power transmission channel has begun to take shape. Three Gorges power and Sichuan hydropower are continuously exported to East China and Guangdong. Clean hydropower in the west has played an important role in the energy-deficient areas in the east, and energy resources have been optimally allocated in the regional power grid.
