摘　　要：边坡稳定性的评价 ,特别是对于具有复杂几何特征的问题 ,应作为三维问题处理。文中提出了一种评价边坡稳定性的三维极限平衡方法 ,并编制了相应的计算机程序。程序使用者可结合工程经验 ,方便地确定可能的滑面 ,对工程上可能的多个滑动方向进行计算、分析 ,并且能方便的计算出各种情况下的安全系数和滑动推力。同时可考虑地下水、地震等因素。最后 ,文中对宜宾翠屏山滑坡进行了稳定分析。In this paper a three dimensional limit equilibrium method is presented for stability assessment of slope with distinct spatial feature and the relevant computer program is compiled. The user of the program can easily select the possible sliding surface with the help of his experience. The calculation can be conducted on a series of sliding directions possible from the engineering viewpoint. The safety factors and sliding force in any circumstance can be calculated easily. The seepage and seismic force and other factors can be considered as well. At last, the analysis of slope of Cuipingshan in Yibin City is given in this paper. [
