摘　　要：2016年9月17日,云南省元谋县黄瓜园镇暴发特大山洪泥石流灾害,尤其是雷布大箐暴发力最强、波及面最广、损毁最严重,并在龙川江堆积区形成堰塞体,致使龙川江干流堵塞19 h,严重威胁上游黄瓜园镇的生命财产安全。以雷布大箐泥石流沟为研究对象,通过实地调查和资料整理,分析了泥石流灾害的地质背景及形成条件,采用RAMMS模拟软件进行数值模拟研究,重现泥石流运动过程;根据运动过程模拟结果,对泥石流进行危险性分区,并将模拟结果与实地调查结果对比,两者差异较小,表明模拟分析较为客观,符合实际。On September 17,2016,a major mountain flood and debris flow disaster broke out in Huangguayuan Town,Yuanmou County,Yunnan Province,with being the most powerful,widespread and severely damaged in Leibudaqing,forming a barrier in the accumulation area of Longchuan River,that causing the main stream of Longchuan River to be blocked for 19 hours,seriously threatening the safety of life and property in Huangguayuan Town upstream.Taking Leibudaqing Debris Flow Gully as the research object,the geological background and formation conditions of debris flow disasters are analyzed through field investigation and data collation.The RAMMS simulation software is used for numerical simulation research to reproduce the movement process of debris flow.According to the movement process simulation results,the risk zoning of debris flow is carried out.By comparing the simulation results with the field investigation results,the difference between them is smaller,which indicates that the simulation analysis is objective and in line with the reality.
