摘要
2010年8月13日苦水沟暴发了较大规模的泥石流,致使主河短时堵塞并溃决,造成了较大灾害。为此研究了苦水沟泥石流形成的物源条件、地形条件、降雨条件及基本特征,根据沟道内取样及泥石流的洪痕断面计算了泥石流的重度、屈服应力、流速流量等静动力学参数,分析了苦水沟泥石流堵河的可能性,并提出相应的防治措施。
In August 13, 2010, Kushui gully occurred large-scale debris flow, blocked tile main river, caused dam break and disaster. This article studies the causes of debris flow of available loose materials, landform, water conditions and basic characteristics. According to the sample and flood tracking section in gully, it calculates the static and kinetic parameters, such as the density of debris flow, yield stress, velocity and flow. And then, the possibility of blocking river by Kushuigou debris flow is analyzed. Finally, some prevention countermeasures are trot forward.
