达摩沟泥石流形成的物质条件分析及防治对策
Analysis on material conditions causing to debris blow and its control countermeasures in Boddhidharma Trench
摘要
Abstract
The Boddhidhanna trench in Mentougou District of Beijing City is an ancient debris blow trench, where have occurred several times severe debris flow disasters. The conditions of geology, landform, hydro meteorology, soil cover and human beings engineering activities are analyzed by using field investigation, geological exploration and laboratory experiment, based on the history of disasters and development characteristics in the drainage basin of Boddhidhanna trench. The properties of debris flow is ascertained to be turbulent or transitional valley-shape debris flow with high density and low viscosity induced by heavy rainfall . The material conditions are primarily studied by the means of particle analysis, electron microscope scanning, X-ray diffraction analysis and laboratory experiment. Finally, the comprehensive control countenneasures including biological measures, engineering measures, environmental protection, economic development, monitoring and warning system and emergency system construction, and so on, are put forward.关键词
