An elastoplastic shear strength reduction FEM is used to analyze the stability of excavation slope.

用强度折减有限元方法对开挖边坡的稳定性进行了较为全面的研究。

Stability method based on slip surface FE stress and shear strength reduction method are two principal methods for FEM slope stability analysis.

基于滑面上应力分析法和强度折减法是边坡稳定有限元分析方法中两类主要的方法。

So the elastic - plasticity model is more compatible to slope stability analysis by FEM with shear strength reduction.

因此，弹塑性模型更适合于强度折减有限元法分析土坡稳定性。
