摘要

"5·12"四川汶川大地震导致灾区地质灾害危险性大大增强,严重影响了周边居民的生命财产安全。都江堰市虹口乡红色干沟泥石流灾害隐患点是其中之一。根据泥石流的成因、类型、规模,以及泥石流的活动特征,对泥石流活动进行了危险性评估,指出泥石流防治工程方案应采用以排为主,适当拦挡的原则,建拦挡坝用以消能、调节泥石流流量;建防护堤用以限制泥石流漫流,对居民区进行有效防护。
"5·12" Wenchuan Earthquake in Sichuan province in 2008,increased the risks of geological hazard in disaster area,and seriously affected the lives and property of surrounding residents.Gangou debris flow in Hongse village in Dujiangyan city is one of hidden points.This paper discribed the cause,type,size of debris flow,analyzed its activity characteristics.Based on these,it conducted the risk assessment;proposed control engineering program of debris flow under the principle of discharging mainly and blocking appropriately,building landslide dam to dissipate energy and regulate debris flow;building protecting dikes to limit the overflow of debris flow,and making effective protecting measures in residential areas.
