摘要

提出了一种基于坡面网格全局搜索土坡临界滑动面的综合优化方法。该方法较好地结合了几何优化和数值优化长处，原理简单，若辅以一定的经验分析，能较高效地得到土坡临界滑动面。通过2个实例计算表明，该方法计算搜索结果具有较好的稳定性和完备性，并且适用于一些复杂的工程土坡。

Abstract

Based on soil slope face grids

a new method is put forward to globally search critical slip surface on slopes. It has preferably utilized both optimization advantages of geometrical and numerical model. Furthermore

its theory is easily intelligible. If assisted by experience analysis on some degree

it will more efficiently get the critical slip surface on soil slope. Two examples are given; the results are both of good convergence and integrity. The method is applicable to some complex soil slopes.
