黄土滑坡尤其是地震作用下的黄土滑坡历来是我国西部广大地区一种突出而严重的地质灾害。本文研究了一种采用遗传算法基本思想和原理确定黄土斜坡“最危险滑裂面”、并以此为基础进行稳定性分析的新方法。实例的验证表明，与传统方法相比，该方法更准确、更高效，具有较好的实用性 Loess landslides, especially loess landslides under the earthquake, have always been a prominent and serious geological disaster in vast areas in western China. In this paper, a new method of determining the “most dangerous slip surface” of loess slopes using the basic idea and principle of genetic algorithm is studied. Based on this, a new method of stability analysis is proposed. The verification of the examples shows that the method is more accurate, efficient and practical than the traditional methods
