“…Among them, the crest elevation of the initial dam is 2480.0m, with a height of 64.0m and its slope angles is 1:2.0, whcih constructed by siltstone. The Tailing dam was made by upstream method with a slope ratio of 1:4.5, a total height of 130.0m and a capacity of 4.398 million m 3 .…”

A finite element model of tailings dam model was used to simulate the steady seepage field and analysis the stability under different working conditions. The head contour, velocity, seepage flow and seepage gradient was analyzed. The stability against sliding in this tailings dam was analyzed with the help of the simplified Bishop method which is based on rigid body limit equilibrium coupled with seepage force. The security coefficient under different working conditions was calculated. The analysis result shows that the safety factor meets the specification requirements, and which provides reference for the stability evaluation of tailings dam.

“…A large amount of tailing dams is built to store the tailings with Chinese economic development. At present， there are more than 2000 tailings dams, and about 1500 of which has formed a certain scale in china [1][2] . The tailings dam is a special kind of hydraulic structures, with a huge dam volume, loose accumulation and continuous changing dam section during operation.…”

A finite element model of tailiings dam was used to analyze the dynamic responses of the stress field, displacement and acceleration of the dam with the dynamic time-history response analysis method in this paper. The time-history curves of different responses were obtained. And an evaluation for dynamic stability of the tailings dam was also discussed. The analysis result shows that this case can provide a certain reference value for the dynamic calculation and the dynamic stability analysis of tailings dam under seismic load.
