G217线K636+100处泥石流灾害特征及危险度评价

摘要

G217线K636+100处泥石流沟位于新疆乌苏市南部奎屯河谷上游,该处泥石流沟在每年雨季和融雪季节均多次发生泥石流灾害,对G217线过往车辆及道路本身带来不利影响.在对该泥石流沟地质环境条件分析的基础上,结合泥石流灾害具体特征,采取危险度评价分析方法对G217线K636+100处泥石流灾害进行分析,得出该泥石流沟属中度危险的泥石流沟.%The debris flow gully at K636+ 100 of No.217 Line is located in the upper reaches of northern Kuitun river of Wusu county in Xinjiang,there are lots of debris flow disaster in the study area during the rainy season every year,which brings adverse effect to the vehicles and the road itself.Based on the analysis of geological conditions at the study area,combined the characters of the debris flow,the debris flow disaster at the K636+ 100 of No.217 Line is analyzed by the method of risk assessment,and drawed the conclusion that the study area belongs to the intermediate risk debris flow.
