摘　　要：将强度折减法应用于边坡稳定性分析中,折减土体强度,代入有限元程序进行计算,直至计算不收敛,此时的折减系数即为安全系数.结合工程实例,对比强度折减法的边坡稳定性有限元法和传统极限平衡法的计算结果,表明基于强度折减法的边坡稳定性有限元分析是可行的.By using the strength reduction method in the analysis on slope stability,the soil strength is reduced,so that the numerical non-convergence occurs,and the safety factor is obtained.With a case study,the result analyzed by the traditional method is compared with that by strength reduction FEM.It is indicated that strength reduction FEM is appropriate to stability analysis of slope.
