Anslysis on formation mechanism and deformation influencing factors of Muyubao landslide in Three Gorges reservoir area

The water level in three Gorges reservoir periodically and concentrated rainfall are the main factors influencing landslide, both from the slide weight of the soil, groundwater, physical-mechanical properties of rock and soil aspects cause varying degrees of impact on landslide stability. Through the study of singing landslide, landslide rainfall and reservoir water level fluctuation, there is a strong correlation between fragile geological structures, rainfall and reservoir water level fluctuation of three coupled deformation due to landslide.
