承德围场县西山庙台沟泥石流危险性分析

庙台沟位于河北省承德市围场县县城西山,曾发生山洪泥石流灾害.为了掌握庙台沟泥石流的运动变化规律,更有效地减小泥石流的危害,通过对庙台沟的地形地貌、物源、水源的勘察分析,计算得出了泥石流的容重、流量、流速、冲击力等参数;针对其形成条件和基于数量化理论,对该泥石流的危险性进行了分析及评估,进而为相关工程的评价及防治提供参考.

Debris Flow Risk Analysis of Western Hill Miaotai Valley in Weichang County of Chengde

The valley lies on the western hill of Weichang County in Chengde district,which have experienced debris flow in the past. To understand the law of debris flow movement and reduce the dangers of debris more effectively,this paper,based on the survey and analysis of the temple ditch topography,material sources and water sources,calculated the parameters,including discharge of debris flow,the velocity and the impulsive force of debris flow,analyzing and evaluating the risk of debris flow according to the forming conditions and numerical theory,which can provide reference for relevant engineering evaluation and prevention.
