چکیده
In this paper using the upper bound limit analysis method, stability of soil slope, uniformly surcharged at the crest was investigated. According to the soil behavior at the failure state, a continuous failure criterion nonlinear function of confining stress and soil initial density, was considered. The stress field along the slip surface is entered into the limit analysis formulation according to the Airy stress function. The ultimate uniformly distributed load was obtained by optimizing the virtual work equation. The effects of different parameters such as slope angle, soil unit weight and initial density have been investigated. Considering the nonlinear effects of confining stresses has led to a reduction in the ultimate load. This reduction is more obvious in slopes with lower angles. According to the proposed formulation, with increasing soil density, the ultimate load of the slope stability has increased. The results for different slope angles, were compared with those obtained from the limit equilibrium-based methods. The ultimate loads of the proposed method are in some cases lower and in some cases more than the results of different methods based on limit equilibrium.
