| 摘 要： | 在野外调查的基础上,针对金沙江乌东德库区工程地质条件,选取坡度、地层岩性、地质构造、岸坡结构等10个与滑坡发生相关要素作为库岸滑坡灾害危险性评价因子,基于模糊综合评判法模型的改进层次分析方法,对乌东德库区库岸滑坡灾害进行危险性评价。研究结果表明:乌东德库区可划分为高危险区、中危险区、低危险区和极低危险区4个区域;所占库区面积比例分别为6.64%,5.77%,60.20%,27.39%,为库岸滑坡的防灾减灾管理和治理提供了支撑。

| Abstract: | According to filed investigation on the engineering geological conditions of Wudongde reservoir area in Jinsha River, we selected slope angle, formation lithology, geological structure, bank slope structure and other 6 factors to assess the bank slope landslide hazard. Fuzzy comprehensive evaluation (FCE) model and modified analytic hierarchy process (AHP) are employed for the hazard assessment. Results revealed that the Wudongde reservoir area can be divided into high risk area, medium risk area, low risk area, and extremely low risk area, respectively accounting for 6.64%, 5.77%, 60.20%, and 27.39% of the whole area. The result provides support for the prevention, reduction, and governance of bank slope landslides. |
