摘　　要：分别选用极限平衡法中的瑞典圆弧法、毕肖普法和简布法,有限元法与极限平衡法结合的方法以及有限元强度折减法,应用ANSYS软件对某尾矿坝进行了静力稳定性数值分析。通过应用不同方法对尾矿坝的静力稳定性计算,得出了此尾矿坝的稳定安全系数和可能滑动面形状,结果表明数值方法在尾矿库坝体稳定计算中具有显著优势,结果能直观而有效的反映尾矿坝的稳定性。The stability analysis of tailing dam was carried out by the ANSYS software. The limit equilibrium method （Fellenius method, Bishop method and Janbu method）, the combining FEM with limit equilibrium method and strength reduction FEM method were used for the stability analysis. The main procedure of tailing dam stability analysis by ANSYS software was summarized. From the stability calculation of tailing dam with different method, the safety factor and circular slip surface of tailing dam were obtained. The calculation results show that the numerical method is suitable for the tailing dam stability analysis, and can directly present the stability of tailing dam.
