Abstract:

Much attention has been paid to the development of the analysis method for slope stability, which is an unsolved problem in the classical soil mechanics till now. Based on the previous analysis methods and slope failure mechanism, a convenient approach, slope centrifugal method, is presented to calculate the safety factor of slope stability in the current work. In detail, the horizontal acceleration is applied on a slope and the value of the acceleration increases until that the slope failure happens. The safety factor can be obtained considering both of the centrifugal and the gravity on the failure slope. The comparisons between the presented method and the previous methods, e.g. the traditional limit equilibrium method and the finite element intensity discount method, is given by an example; and the sensitivity analysis of various physical parameters is given to show the validity of the presented method for analysis of slope failure. Results also show that the safety factor obtained by the presented method depends on the elasticity of the material in slope, slightly.

Key words: slope centrifugal method, slope stability analysis, safety factor, sensitivity analysis
