摘要
介绍了松树林泥石流流域特征,根据不同类型分别统计了坡面侵蚀物源、沟道堆积物源及不良地质灾害等松散物源,分析计算了泥石流容重、流速、流量、一次冲出量等特征参数,统计了泥石流的威胁对象,根据危险等级,提出了防治对策。
The characteristics of the debris flow in the Songshulin were introduced,and the different types of the loose solid material sources such as the source of the erosion, the source of Channel deposits and the geological disasters were researched. The characteristics Parameters such as the bulk density, flow rate and total discharge of debris flow were analyzed. Threat object were counted. According to the danger level, prevention and control measures were put forward.
