摘　　要：将强度折减法应用于边坡二维、三维稳定性分析中,并与传统极限平衡分析法的计算结果做了比较,得出强度折减法三维有限元分析边坡稳定性是可行的,对影响边坡稳定的因素进行了研究分析,并分析了三维边坡在面荷载大小相同但作用面积不同时的安全系数,指出边坡稳定具有三维效应,对边坡稳定分析有一定的指导意义。The strength reduction method is used for the analysis of two-dimensional and three-dimension slope stabilities, whose results are compared with the result of limit equilibrium method, the result shows the strength reduction method is feasible. The factors influencing slope stability are studied, and it is analyzed the safety factor of a three-dimensional slope with same surface load, yet a different active area. It is also pointed out that slope stability has three-dimensional effect, which has some guidance for analyzing the stability of a slope.
