At present,there are three criteria for evaluating stability of slope in elastoplastic FEM based on SSR technique including the abruptness of the displacement,the convergence of numerical computations or deformation at a certain characteristic location and connectivity of plastic zone.An example homogenous soil slope is analyzed by using the elastoplastic FEM based on the SSR technique and their computed results are compared with the solution of limit equilibrium.It is shown that the safety factors computed by using the three criteria are almost identical to the solution of limit equilibrium method.It is also proven that the three criteria are feasibility to analyze the homogenous soil slope.
