| 摘 要： | 介绍了强度折减法的基本原理，并在数值分析过程中，以位移计算的不收敛作为边坡达到极限平衡状态的标准，利用ABAQUS有限元分析软件对含有软弱下卧层上边坡的稳定性进行了；限元计算，分析上部与软弱下层土体的弹性模量、泊松比、密度、抗剪强度对边坡稳定性的影响，得出以下结论：土体的抗剪强度与密度对边坡稳定与滑动面的形成有着显著的影响，而泊松比与弹性模量的影响很小．

| Abstract: | The basic principle of shear strength reduction method is introduced. In the process of numerical analysis, we recommend convergence of displacement calculation as the standard of slope reaches limit equilibrium state; and use ABAQUS finite element analysis software and finite element method to figure out the stability of the slope which contains the soft substratum, and analyse the influences of elastic modulus, Poisson＇ s ratio, density and shear strength of the upper and lower soft soils on the stability of the slope. From above analysis, a conclusion is drawn as follows： the soil＇s shear strength and density have a remarkable effect on the slope＇s stability and the formation of landslide; while Poisson＇s ratio and elastic modulus have a little impact. |
