摘要
重庆是典型的山地城市,矿产资源丰富,降水充沛,为矿山泥石流灾害较为严重的城市。为分析重庆山区孕育矿山泥石流灾害的地质环境特征,本文选取渣堆坡角、渣堆高度、渣堆堆积时间等13个因子构建了矿山泥石流潜势度评价指标体系,利用层次分析法确定各指标权重,建立了矿山泥石流潜势度综合指数评价模型,并以秀山溪口矿山泥石流为研究对象,通过计算得到研究区矿山泥石流潜势度指数为8.51,区内地质环境孕育矿山泥石流的潜在能力高,评价结果与实际情况吻合。
Chongqiong is a typical mountain city with rich mineral resources and abundant rainfall,and it＇s also a city that the mine debris flow disaster is serious. To analyze the geological environment characteristics of Chongqing mountain area which maybe give birth to mine debris flow,the assessment index system of potentiality degree was constructed with the angle,height,accumulation time of slag heap and other 10 indices,the weight of each index was calculated by the analytic hierarchy process and the comprehensive index model was established. Taking a mine debris flow in Xikou of Xiushan as an example,by calculating,the index of potentiality degree is 8. 11,and it means that the potential ability which may induce mine debris flow is high in this area. The assessment result is consistent with the actual situation.
