In this paper, the principle and formulas to evaluate the stability of slopes with ground water are introduced,the equilibrium functions of element have been derived considering the influence of the pore pressure, and the formulas of water pressure on boundaries of element are also discussed. The decided critical sliding surface and the minimum factor of safety are searched by employing an optimization process when the ground water is considered. It is indicated that the stability of a slope acted with ground water is much worse than that of the slope without ground water from a numerical example.
