Abstract: Based on the theory of lower bound limit analysis, finite element are used to discretize the mechanism. The statically admissible stress fields that are satisfied the conditions of equilibrium, stress boundary, yielding and stress discontinuity, are constructed. The pore water pressure is considered as an external force, similar to gravity. By using the idea of linear programming, lower bound limit analysis models of mathematical programming for slope stability are established; the model can evaluate the safety factors and stress field of lower bound. Finally, taking two classical soil slopes for examples of calculating slope stability, the comparisons among the results of various methods are made. The results indicate the correctness of the method and the program.

Key words: plastic limit analysis, lower bound, pore water pressure, slope stability, safety factor
