基于层次分析法的灰坝桥沟泥石流危险性评价

Risk Assessment of Huibarqiaogou Debris Flow Based on AHP

灰坝桥沟泥石流地处四川省攀枝花市西部山区,又处于金沙水电站附近区域,它的爆发会给当地人们生命财产及生态环境等造成严重影响,因此,对其进行相关研究具有重要意义。根据四川省近年来泥石流灾害情况进行分析,总结了该地区泥石流主要特点,并利用现场勘察资料、室内试验数据及部分相关资料,对灰坝桥沟泥石流进行了危险性评价。

Huibarqiaogou debris flow is located in the western mountains of Panzhihua City, Sichuan Province and but also in the vicinity of Jinsha hydropower Plant. Its outbreak will seriously affect the local people＇s life and property and the environment. Therefore, it is important to do this research. According to analysis of debris flow appearing in Sichuan Province in recent years, this paper summarized the main features of debris flows appearing in this area, and performed risk assessment for Huibarqiaogou debris flow by field survey data, laboratory test data and some relevant information.
