| 摘 要： | 山地地区由于特殊的地形地质条件，滑坡灾害较为频繁，由此造成了较大的生命、财产损失。常用的滑坡稳定性分析方法没有考虑滑坡稳定性受很多不确定性和随机性因素的影响，其结果与实际存在一定的偏差。以三峡库区兴山县望岭岩滑坡为实例，将常用的滑坡稳定性分析方法与可靠度理论Monte-Carlo法有机结合，考虑岩土体重度、黏聚力、内摩擦角的不确定性，计算得到滑坡体可靠度指标，所得结果更加符合实际情况。

| Abstract: | Landslide disasters frequently occur in mountain area due to the special terrain and geological conditions,which cause large loss of life and property.Conventional stability analysis methods often obtain results that do not conform to practice because they don't consider the uncertainty and randomness of landslide.Taking the Wanglingyan Landslide in Xingshan County in Three Gorges area as an example,we combine the traditional analysis method with Monte-Carlo method,considering the uncertainty of density of ... |
