Abstract:To know the dynamic characteristics and stability of high tailings dam located in strong earthquake area based on the centerline embankment method with waste rock, The FEM is used to model the seepage, static conditions and the dynamic response of centerline embankment tailings dam with waste rock. The acceleration response, liquefied region and stability of dam under earthquake loads are analysised. The results show that the phreatic line of tailing dam is low, and the liquefied slip region cannot be formed under earthquake with M=9.0, the response of acceleration of tailing dam is less and amplifies 1.99 times. The minimum safety factor of the dynamic time history of the dam is 1.055, which can meet the need of specification. The results can be applied to guide the designing, research and seismic strengthening of high tailings dam located in the strong earthquake area.
