What are the components of the Three Gorges Project?

The hub is mainly composed of concrete gravity dam, hydropower station, double-line multi-stage ship lock and first-line vertical ship lift. Maximum dam height 175m, crest elevation 185m, crest length 1983m, normal water level 175m and initial water level 156m. The total storage capacity is 39.3 billion cubic meters, and the flood control storage capacity is 2210.5 million cubic meters. 26 hydropower stations have been installed, with a total of 6.5438+0.82 million kilowatts. The construction policy of "one-level development, one-time completion, water storage by stages and continuous migration" is adopted. The resettlement adopts the development immigration policy, which makes the production and life of immigrants better arranged. In 2003, the first wholesale motor set was completed in 2009. The static investment required for the project is 900.9 billion yuan (65438+1price level at the end of May 1993). Among them, the investment in hub projects is 500.9 billion yuan and the investment in reservoir resettlement is 40 billion yuan. After the project starts to generate electricity, the power generation income of itself and Gezhouba Water Control Project can basically meet the needs of construction funds.
