Lengzhuguan Dadu River Power Plant

Debris flow is a common geological disasters in mountain areas, The outbreak of a sudden, Against the very serious.By the debris flow by the Department, Washed away roads, railways, bridges, water facilities, Etc. Blocked the river, caused flooding.The study area on the left bank of the Dadu River of the study area distribution Jiang Tsui trenches,Ah rake groove,jiaoji Ditch three Large debris flow gullies .This three debris flow gully Mizoguchi fans accumulation significantly, History shows that large landslides have occurred. The study area is located in Ganzi Tibetan Autonomous Prefecture of Sichuan Province, Kangding County,In this area have some Important township such as guzan town,maiben rural. Traffic developed, densely populated,There are Lengzhuguan more gold Ping Water Conservancy and Hydroelectric Power Station and other important facilities.Three mud-rock flows have a large number of people living trench.The event of large mud-rock flows, people's lives and property would be a huge security threat, More likely to be on the water conservancy and hydropower facilities adversely affected.Obviously the study of debris flow characteristics of gully development in the study area is necessary. So this paper is on the basis of a comprehensive survey, statistics, analysis,Through the analysis of the development of characteristics and dynamic characteristics , Discussion the effects of debris flow, Have great significance of disaster prevention and mitigation in study area.In this paper by the means of the collection of Previous research data,ETM image ??rpretation,Spot survey at the scene. System on the study area on debris flow gully development environment from the natural environment, meteorological and hydrological, geological structure, hydro-geological aspects. From the basic characteristics of debris flow, debris flow dynamic characteristics of the three aspects of the development trend of debris flow on the debris flow research. Finally, the above contents of the volume of sand lost from the debris flow on the water works, the role of debris flow erosion and accumulation of the effects of road debris flow analysis of two aspects of the project effects.
