Research On The Formation Mechanism Of Maliugou Slope Debris Flow Through Model Test

This paper relies on a major national scientific and technological special research project of geological disaster monitoring and early warning sensor network development and application. Based on field survey, data collection, laboratory experiments and numerical simulation, this paper analyzes and explains the characteristics, explores the formation of Maliugou debris flow mechanism, lays a foundation for the identification and preliminary forecast of Maliugou debris flow. The research results obtained in this article are as follows:(1)Through the collection of survey data, field investigation and soil test, this paper identifies the hydrogeology and engineering geology condition of Maliugou, such as rock characteristics, material composition and characteristics of Maliugou.(2) Selected typical slope, we build physical test model and did the experiment under three conditions of 60mm/h,90mm/h and 120mm/h.(3) Based on the experiment, we build numerical model. Through the software GeoStudio2007, we respectively simulated seepage field, stability in two-dimensional.(4) Combining with numerical simulation, we analyzed the model test data and phenomenon and drew a related conclusion.
