| 摘 要： | 大岗山水电站库区泥石流地质灾害严重影响水电站的安全运行。通过高精度遥感解译及实地调查，运用层次分析法（AHP）从泥石流的地貌条件、物源条件、激发条件、历史活动强度中选取14个基础指标作为评价泥石流危险度的因子，建立库区泥石流危险度评价模型,对库区18条泥石流进行单沟危险度分析，认为其危险度以中、低度为主，分析结果与常用泥石流危险度及基于地貌信息熵的危险度计算结果有较好的一致性。

| Abstract: | The geological hazard of debris in the reservoir area of Dagangshan Hydropower Station significantly affects its safe operation.Through high-precision remote sensing interpretation and field investigation,we chose 14 basic indexes among the geomorphic condition,material source condition,excitation condition,historical activity intensity etc.as evaluation indexes for risk degree assessment of debris using AHP method.The model of debris risk degree evaluation is established and the single risk degree of 18 de... |
