摘要
基于对中国西部黄土地区大量地震滑坡实例的考察分析，对影响黄土斜坡稳定性的各类因素尤其是地震因素进行了分析，讨论了黄土斜坡滑裂面的产生机制及几何特征．在此基础上提出了一种基于随机搜索法和遗传算法确定黄土斜坡最危险滑裂面，进而对区域黄土地震滑坡进行预测的方法．以回回川滑坡为例进行了验证．结果表明，该方法具有较好的效果和实用性．
Based on a research for a great number of loess landslides caused by earthquakes in the northwest China,several factors which have an effect on stability of loess landslides are analysed,especially analysing the effect of earthquake.The mechanism of loess landslides to occur and geometric feature of sliding surface in loess slope are discussed.A fundamental approach forecasting the most dangerous sliding surface in loess slope by traditional random scouting method and genetic algorithm is introduced.A new method forecasting loess landslides in a region by using scouting analysis is suggested and it is proved to be effective and practical in test of Huihui Chuan landslides.
