The research and demonstration of some major geological problems of Three Gorges Project

摘要

The research process,main contents,methods and conclusions for some major engineering geological problems of the Three Gorges Project (TGP) are reviewed and introduced,including dam site selection,regional tectonic stability and seismic activity,stability of reservoir bank and reservoir-induced earthquake.Meanwhile,the above mentioned engineering geological problems are evaluated according to the preliminary test results since TGP operation and impoundment in 2003.
