摘　　要：在广西龙胜镇浸沟泥石流勘查的基础上,从泥石流地质灾害形成的地质环境条件入手,对龙胜镇暴雨型泥石流的形成机理进行研究。分别在流通区采用拦栅坝对物源区的物源拦截,在堆积区采用修建导流槽、坡面排水沟、导流堤、挡土墙等工程措施进行综合治理。运用层次分析法对工程防治效果进行评价,结果表明,浸沟泥石流防治工程效果良好。这一泥石流的治理思路可为同类泥石流地质灾害治理提供借鉴。Based on the investigation of gouge debris flow in Longsheng Town,Guangxi,the formation mechanism of rainstorm debris flow in Longsheng Town is studied from the geological environment conditions of debris flow geological disasters.The flow area is intercepted by the barrier dam in the circulation area,and the accumulation area is comprehensively controlled by the construction of diversion channel,slope drainage ditch,diversion dike,retaining wall and other engineering measures.The analytic hierarchy process(AHP)is used to evaluate the effect of the project.The results show that the effect of the project is good.This idea of debris flow control can provide reference for similar debris flow geological disaster control.
