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.
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。

On the basis of the theory of dynamic mechanics and elastic-plasticity mechanics, the asphalt pavement of semi-rigid subbase on the soft clay ground is analyzed using the axisymmetric FEM.
