【摘要】 传统的边坡稳定性分析方法往往是基于单因素影响的分析来判断各项因素对边坡稳定性的影响 ,而对于各项影响因素的复合影响及之间的主次关系难以确定。基于边坡系统本身的不确定性和复杂性 ,引入灰色系统的灰色关联分析理论 ,以都江堰周家院场区为实例 ,考虑影响因素 :抗剪强度指标内聚力与内摩擦角、滑动面坡度、残坡积层厚度、岩石渗透系数、斜坡高度、进行边坡稳定性的灰关联分析 ,最后得出结论 :在川西北山地的粘性土边坡稳定性影响因素的分析中 ,应着重考虑主导因素岩土内聚力和残坡积层厚度的作用更多还原

【Abstract】 s: Natural disasters relative to slope stability do great harm to people’s life. It is very important to analyze slope stability. Traditional methods always judge the influence of each factor on slope stability on the basis of a single influential factor analysis. And it is is difficult to make sure of the relationship among multiple influences and priority of each factor. Because of the uncertainty and complexity of slope the system , this paper uses gray correlation analysis of a gray system to analyze the project of Zhoujiayuan site in Dujiangyan. This method chooses C, φ, α, h, K 0, H as influential factors. Finally, it makes a conclusion that when people analyze the slope stability of the northwest of Sichuan Province, it is important to consider the main influential factors: C, h .更多还原
