Different functions for principal stress were used as elastic medium failure conditions at the boundary with the crushing zone and plasticity within the latter based on Coulomb rule.

以库仑定律作为强度破坏准则，破碎区边界上的弹性介质和它内部的塑性介质的破坏条件分别采用了不同的主应力函数。

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。
