A key backbone project for the harnessing and exploitation of the Yangtze River, the Three Gorges Project consists of the pivotal dam project, a power transmission and transformation project, and a resettlement project （see Figure 1）. The axis of the Three Gorges Dam is a total of 2309 m long, the dam crest level is 185 m, and the normal pool level is 175 m. Navigation structures include a per- manent navigation lock and a ship lift. The permanent navigation lock is a double- line, five-level, multistage flight lock with a designed annual unidirectional ton- nage capacity of 50 million tons. The ship lift is a single-linG one-level, steep-lifting type with a lifting height of 113 m, and a gross ship box weight of about 15 500 t—— the largest lifting height and weight in the world.
