四川省九龙县石头沟泥石流动力学特征及其危险性评价研究

泥石流是山区常见的地质灾害之一，但由于其爆发频率低、爆发前兆不易识，往往难以引起人们的重视，一旦爆发泥石流，就容易造成灾害。研究泥石流的动力学特征是理解泥石流成因、特征及工程设计参数的重要途径，可为泥石流治理提供科学依据。在对石头沟进行实地调查所获取一手资料的基础上，对该沟泥石流的动力学特征及成因进行分析、计算，并对其危险性做了定量评价，研究结果可为石头沟泥石流的治理及防灾减灾提供可靠依据。

Shitougou Debris Flow Dynamic Characters and Its Hazard Risk Assessment in Jiulong of Sichuan Provience

Debris flow is one of the geologic hazard which often is seen in mountain area, but it is difficult to be recognized because of its low frequency and indiscernible character of occurrence. Once the debris flow occurred, the heaven lose will be happened. Studying the dynamic characteristics and hazard risk assessment can help us to know debris flow and provide parameter for prevention engineer design. Based on the field investigation data of Shitougou, the cause of formation is analyzed, the dynamic parameters are calculated and the risk of debris flow is evaluated, which can provide basis data for Shitougou debris flow mitigation.
