Abstract:
Based on the simplified assumption of equidistant circular slip surface, the model of limit analysis for soil slope stability can be established, the formula for computation of safety factor can be obtained when the theory of soil plasticity limit analysis is used. The method had considered not only the effect of the energy dissipation rate produced in the slip surface, but also the effect of the work rate produced by selfweight, seismic force and pore water pressure. It is a modified method of soil plasticity limit analysis, and can be used to evaluate the stability of soil slope.
