中文摘要：

最小势能法是边坡稳定性分析的新方法,而滑面上储存的剪切势能是滑体系统总势能不可或缺的一部分,因此针对任意形状滑面,提出一种考虑滑裂面上剪切势能的最小势能法。为验证改进后最小势能法的合理性,将其与Bishop法从理论以及算例方面进行了对比分析。结果表明：改进后的最小势能法是合理且可行的,可以用于边坡稳定性的评价;最小势能法无需划分条块及迭代,分析计算过程简洁,相比Bishop法有一定的优势,便于在工程中推广应用。

英文摘要：

The method of minimum potential energy is a new method in slope stability analysis, and the shear potential energy in the sliding surface is an indispensible part of the total potential. Therefore, a minimum potential energy method is put forward by consideration of the shear potential energy of the sliding surface. To validate the feasibility of the method, it was compared with Bishop method theoretically and through examples. The results show that the minimum potential energy method is feasible and reasonable, which can be used in the evaluation of slope stability. The minimum potential energy method is simple and convenient for slope stability analysis, in which the slice division and iteration are not required, therefore, it is superior to Bishop method and easy to be applied in engineering.
