Combining the advantages of the limit equilibrium slice method and finite element method, the stress distribution on the sliding surface is concluded from the analysis result of finite element method. Through simple transformation, the normal stress distribution on the sliding surface can be obtained which could be used as initial stress on the sliding surface of slope. Then two unknown parameters were introduced to make correction for the normal stress which will led to the unknown parameter and safety factor of slope by substituting revised normal stress on the sliding surface into limit equilibrium equations and several simple iteration. By comparing the stability calculation results of the method introduced and other normal methods in specific engineering, the feasibility of the introduced method is verified.
