The Review Of Debris Flow

Mudslide was caused by heavy rains, flash floods earthquake mixed with gravel and clay along the slope of the whereabouts of geological disasters, occurred in a mountainous area, sphere of influence, of long duration, caused by disasters and so on.At this stage, debris flow studies have received considerable attention in the world, especially in some earthquake-prone countries, such as China and Japan. To on China mudslides research of experience and in recent years mudslides research latest results for summary, on mudslides research future of development direction made prospect, paper combines mudslides research system and mudslides occurred law, using compared analysis method, chart show method, method, described has mudslides of basic defines, mudslides research of important significance, both at home and abroad mudslides research have history status, mudslides formed causes, mudslides formed mechanism, mudslides body of flow special features research, including flow, and velocity and capacity heavy of calculation. By selecting index system of debris flow in the general classification, describes several study on the mathematical model of debris flow, analyzes the debris flow distribution in time and space, the basic characteristics of mud-rock flow occurred in all regions. After understanding the hazards of debris flow based on debris evaluation method and evaluation system was introduced. Introduces several ideas and common means of control debris flow disasters, including zoning hazard degree of debris flow, debris flow prevention engineering and non-engineering measures.Finally, the history and present status in research on debris flow analysis, presented problems in the study of mud-rock flow in China, including the study of low frequency debris flow problems such as insufficient attention, and makes predictions about the future direction of study on debris flow development, arguing that future research on debris flow is richer, branch more and more advanced research tools, dependency on 3S and other high-tech growing.
