中文摘要：
堆积层斜坡是第四系及近代松散堆积层的一类斜坡,也是滑坡灾害中主要灾种之一,然而一直以来缺乏专门针对堆积层斜坡的稳定性分级。该文以三峡库区为研究对象,选取堆积层斜坡11个主要影响因子并对单因子进行划分,建立因子层次结构。运用层次分析（AHP）和模糊数学（FM）方法,通过对影响因子进行权重分析以及建立堆积层斜坡稳定性分级隶属函数,将堆积层斜坡稳定性分为四级并建立了堆积层斜坡稳定性分级系统,为堆积层滑坡的合理防治方案提供帮助。最后通过工程实例验证,与极限平衡法结果对比效果良好。
英文摘要：
Accumulative slopes belong to a kind of Quaternary and recent loose accumulation,and it is one kind of main hazard of landslide,however special stability classification for accumulative slopes is lacked in a long time.In this paper,11 influential factors of accumulative slopes in Three Gorges reservoir area are selected and being divided and the factors hierarchical structure is built. Using analytic hierarchy process（AHP） and fuzzy mathematics（FM）,through the influential factors are weight analyzed,the classification membership function for accumulative slopes stability are set up,the stability of accumulative slopes is classified as four and the stability classification system is built,and it provides help for reasonable prevention of accumulative landslide.In the end, through the verification of engineering examples,AHP-FM method obtains good effect as compared with limiting equilibrium method.
