摘　　要：皖南山区地质构造条件特殊,地势险峻,在突发暴雨的情况下易发生泥石流地质灾害。本文根据现场调查,从地质、物源、水源等方面分析皖南山区社屋坑泥石流形成条件,计算泥石流流体重度、流速、流量、一次泥石流过程总量、冲击力、爬高、弯道超高等特征参数,提出工程治理与生物防护相结合的措施,加强泥石流监测与管理力度,构建完整的泥石流防护体系,为皖南山区泥石流调查和防治提供参考依据。Debris flow is prone to occur in the mountain areas of Southern Anhui because of the special geological structure and steep terrain.Based on the field investigation,this paper analyzes the formation conditions of debris flow in Shewukeng which is located in the mountain areas of Southern Anhui from the aspects of geology,material source and water source,calculates the characteristic parameters of debris flow,such as the fluid density,velocity,flow,total amount of primary debris flow,impact force,climbing height,curve superelevation and so on,and scientifically puts forward the measures of combining engineering treatment with biological protection,strengthening the monitoring and management of debris flow,building a complete debris flow protection system,which provides a reference for the investigation and prevention of debris flow in the mountain areas of South Anhui Province.
