摘    要：讨论了地下水作用边坡稳定性分析的运动单元法基本原理与公式,推导了有孔隙水压力影响的单元静力平衡方程和单元边界水压力的计算式.采用运动单元法对地下水作用边坡最危险滑动面进行全自动搜索,研究结果表明,地下水作用边坡的安全系数远小于无地下水作用边坡的安全系数.

Abstract: In this paper, the principle and formulas to evaluate the stability of slopes with ground water are introduced,the equilibriumfunctions of element have been derived consideringthe influence of the pore pressure, and the formulas of water pressure on boundaries of element are also discussed. The decided critical slidingsurface and the minimumfactoro safety are searched by employing an optimization processwhen the groundwater is considered. It is indicated that the stability of a slope acted with groundwater is much worse than that of the slope without groundwater from a numerical example.
