According to the element stresses, strains and displacements calculated by the Finite Difference Method (FDM), the Finite Arc Method based on the limit equilibrium theory and the Strength Reduction Method with deformation trend as the failure standard are established. The critical slip surface of slope and the minimum safety factor are obtained by the two new methods. A classical slope case is specialized to validate these methods and the feasibility in slope engineering is proved by the influence analysis of the results.
