在分析刚体极限平衡法理论的基础上，基于 GeoStudio 软件采用三种简化方法搜索了滑动面、计算了稳定安全系数并对各条块受力作了分析，结果表明：瑞典法计算得到的安全系数有较大的误差；而 Spencer 法和 Morgenstern-Price 法计算得到的安全系数相对准确。%On the basis of analyzing rigid limit equilibrium method theory,based on the GeoStudio software,the paper searches three simplified active surface,calculates stability safety coefficient,and analyzes their stress. Results show that:the safety coefficient with Swedes method has bigger error,while the safety coefficient with Spencer method and Morgenstern-Price method is relatively accurate.
