摘　　要：基于有效应力法的EFES3D程序,采用E-B模型对陶家沟尾矿坝进行了数值模拟和边坡稳定分析,得出坝体变形场,应力场及边坡稳定安全系数。通过计算得出坝坡的静力稳定最小安全系数为1.26,说明尾矿坝在静力状态下是稳定的,为陶家沟尾矿坝安全评价提供依据。可以看出,在上游加高法方案下,尾矿坝坝坡有较大的向上涌起变形,不利于尾矿坝的稳定安全。为此提出在加高方案中加强排渗设施建议。Based on the effective stress EFES3D procedures,the article used E-B model to do the numerical simulation and the slope stability analysis for Taojiagou tailings dam.By finite element calculation,the results were obtained as the static dam slope stability of the minimum safety factor was 1.26,witch indicated tailings dam in the static state was stable.It can provide a basis for the safety assessment of Taojiagou tailing dam.So it can find out that the dam slope up rush and safety factor of slope reducing under the upstream heightening design plan,which is not profitable for dam stability and management.Also the measures edded drain pipes in the design are proposed.
