利用有限元强度折减法对某尾矿坝的边坡稳定性进行了计算，同时利用简化毕肖普法和瑞典圆弧法对该坝体的边坡稳定性进行了计算。通过对比分析，有限元强度折减法的计算值与考虑条块间作用力的简化毕肖普法的计算值基本一致，证明基于有限元理论的强度折减法的计算结果是合理的，其安全系数值可以作为该尾矿工程定量判断的依据。
The slope stability of the tailing dam is calculated by using strength reduction FEM calculation ,and at the same time the stability is calculated with the simplified Bishop method and Sweden Arc method ,two kinds of tradi-tional methods.Through comparative analysis,the calculation of the strength reduction FEM and traditional method were basically consistent,indicating that the strength reduction method result based on finite element theory is reasona-ble and the safety factor can be used as the quantitative basis of judgment in tailings engineering .
