Abstract
In order to study the causes of debris flow in Shangyue Village and the hazard zoning of the channel,field investigations were combined with Massflow numerical simulation.The source,water source,channel topography,drainage DEM and other characteristics of the debris flow were investigated on site,and the simulated rainfall data and other relevant parameter information were calculated.Using Massflow and ArcGis software,the motion state of the debris flow in Shangyue Village was inverted.In addition,the scope of the dangerous area of the channel is divided,and the simulation shows that the maximum mud depth of the debris flow is 2.857m,the maximum velocity is 5.127m/s,and the medium and high risk areas of debris flow account for 63.8%.Combined with the current development characteristics of debris flow in the channel and the simulation results,it is analyzed that the medium and high-risk areas of the channel are large,and the follow-up engineering treatment should be accelerated.关键词
