Taking the deposits slope in the nodal region of Jin'anqiao Hydropower Station as the study object, on the basis of nonlinear dynamic response analysis and strength reduction FEM, the dynamic response of slope in case of earthquake is considered; by strength reduction FEM, the stability safety coefficients of natural slope before and after ponding are calculated so as to obtain the plastic-zone analysis in critical slip of the slope, confirm the failure type, assess the slope stability, and propose the rational treating measures.
