摘要： 以乌东德库岸滑坡为例，充分考虑其发育的地质环境，选取滑坡发育特征、岸坡结构与岩性特征、地质构造与地形地貌特征、灾害诱发因素共4类因子作为滑坡易发性的影响因素.构建单因素分级标准，将库岸滑坡灾害易发性划分为四个等级，即重度易发、中度易发、轻度易发与不易发.应用区间数与集对分析理论，建立基于联系期望概念的库岸滑坡灾害易发性评价新模型，可系统分析滑坡易发性评价指标的区间形式及演化态势.实例分析结果表明，该方法评判结果可靠，且能简化区间数之间关系的分析过程.

Abstract: The paper takes the Wudongde reservoir bank landslide as an example and fully considers the developed geological environment. The four impact factors including development feature of landslide， bank slope structure and lithology characteristics， geological structure and topography characteristics， disaster inducing factors are selected as landslide susceptibility factors. A single-factor grading standard is established to divide the susceptibility of reservoir bank landslide disasters into four levels: severe， moderate， mild and good. Based on the interval number and set pair analysis theory， a new model of connectional expectation for landslide susceptibility evaluation is introduced. This model can be used to analyze variation trend of landslide impact factors. The case study shows that the new method is reliable and can simplify the analysis process of the relationship between interval numbers.

Key words: geological disaster; reservoir bank landslide; susceptibility; interval number; set pair analysis
