Architectural structure of the Three Gorges Project on the Yangtze River;

The Three Gorges Project on the Yangtze River is the largest water conservancy control project under construction in the world today.

The Three Gorges Project adopts the construction scheme of "one-level development, one-time completion, water storage by stages and continuous resettlement". According to the price of 1993 at the end of May, the static investment of the Three Gorges Project is 90.09 billion yuan, including 50.09 billion yuan for the hub project and 40 billion yuan for resettlement.

The total area of the Three Gorges Reservoir is 1.084 square kilometers, and the flooded land area accounts for 632 square kilometers, covering 2/kloc-0 county-level administrative regions in Hubei Province and Chongqing City. The project consists of dams and reservoirs, power stations and navigation structure.

Reservoir: the total length of the dam is 3035 meters, and the elevation of the dam crest is 185 meters; The normal water level is156m at the initial stage and175m at the later stage; The total storage capacity is 39.3 billion cubic meters, of which the flood control storage capacity is 2210.50 billion cubic meters.

Power station: install 32 hydropower units with a single capacity of 700,000 kilowatts, with a total installed capacity of 22.5 million kilowatts; The annual power generation is 84.7 billion kWh.

Navigation facilities: 1 double-track five-class ship lock, which can pass through a fleet of 10,000 tons; There is a 1 vertical ship lift, which can quickly pass through 3000-ton ships; The annual one-way navigation capacity is 50 million tons.
