摘　　要：边坡稳定性影响因素众多,且这些因素相互之间存在复杂的非线性关系。采用Choquet模糊积分建立了边坡稳定性评价模型,选取合理的评价指标并建立标准评价值,依据专家评判并结合层次分析法给出权重,利用Choquet模糊积分对评价信息进行集结。该模型物理概念清晰,建模过程直观简便,实例分析结果可靠。The stability of slope system is affected by so many factors and there is a complex non-linear relationship among these factors. The slope stability evaluation model based on Choquet fuzzy integral is established, in which, some reasonable indexes are selected and the standard evaluation values are set, and then the evaluation weight is calculated based on expert judgment and analytical hierarchy process, and finally the evaluation information is integrated by Choquet fuzzy integral. The case study indicates that the model can make the physical concept very clear, the modeling process is visualized and convenient, and the analysis result is also reliable.
