Abstract: Based on the theory of upper bound limit analysis, the velocities of the nodes are regarded as unknown quantity, with the conditions of flow rule, velocity discontinuity, velocity boundary, the energy-work balance equation, the linear programming model of stability of slope subjected to pore water pressure are established. The pore water pressure is considered as an external force. Then the upper limit value of the safety coefficients of slopes, and the corresponding kinematically admissible velocity fields are obtained. Finally, using the proposed method，the stability of two classical soil slopes are calculated; and the results demonstrate the correctness of the method.

Key words: plastic limit analysis, upper bound, pore water pressure, slope stability, linear programming
