Abstract Xiluodu hydropower station on Jinsha River began to impound water in May 2013，and the deformation of four fractures increased significantly till the October 2013，which appeared a slope of the reservoir bank. So far，the amount of main fractures have increased from 4 to 9，with a tendency of continuous deformation and failure，which lead to a great inconvenience to local people and significantly influence on the normal operation of the hydropower station. Through site investigation and data analysis，the mechanism of its further evolution of the role of reservoir storage was proposed base on early formation mechanism study of the toppling deformation body. Due to influence of incised valley and special geological structure of the slope，nonuniform contraction-toppling deformation was occurred on the slope，which cause a toppling deformation body. Because of the impoundment of the reservoir，the toppling deformation was aggravated by the soft rockmass under the slope caused by water immersion. As a rare failure mode all over the world，a preliminary judgment was made for the stability of the toppling deformation slop by numerical simulations.

Key words： slope engineering slope of reservoir bank water-rock interaction contraction-toppling deformation formation mechanism deformation failure mode numerical simulation
