which is located in the left bank of Qinggan river
a branch of Yangzi river
is one new bedding rock landslide induced by impoundment of the Three Gorges Reservoir. The three-dimensional limit equilibrium analysis method is applied to analyze the stability of Qianjiangping landslide and the landslide triggering mechanism. The factors of safety of the landslide under intensive rainfall and reservoir water fluctuation were evaluated. The computation results reflect that the groundwater has an important infection on the stability of Qianjiangping landslide. The reservoir impoundment and intensive rainfall are the dominant exterior factors triggering the landslide.
