    Abstract:

    Strength reduction method is applied in the slope stability analysis, the soil strength is reduced and calculated by finite element program until the calculation convergence. At this time, the reduction coefficient is the safety coefficient. Combining with the engineering case, the slope stability is analyzed using the strength reduction method; meanwhile, also using Swedish arc method and with the geotechnical engineering design software Tianhan as well as the finite element analysis software ABAQUS to analyze slope stability and compared the safety coefficient. It is concluded that the safety coefficients obtained by these 3 calculation methods have little difference and the coefficient accuracy can meet the engineering requirements.
