Earth-rock dams account for most of the dams which are being built or to be built.The stability of the dam slope is a key issue in the engineering design of the earth-rock dams and the dam of slope stability under strong earthquake is even more the hot issue in the field of geotechnical engineering.The time history analysis was made for a certain high earth-rock dam with software ANSYS.Reliability index was obtained through iterative computations with the help of JC method in reliability calculation method.The safety coefficient of dynamic reliability and minimum reliability index were further obtained,and their analysis result would have wide application value for dynamic stability analysis of high earth-rock dams.
