摘要:泥石流是发生在山区的常见自然灾害,它是由土、石等固体物质与水相混合在重力作用下沿陡峻沟坡运动的饱和流体,其爆发突然、历时短,但造成的灾害十分严重,有时甚至是毁灭性的。2010年8月7日甘肃舟曲特大山洪泥石流灾害所造成毁灭性灾难,伤亡人数之多,财产损失之大成为我国历史上有记录以来的泥石流灾害之最。本文作者通过查阅大量文献资料及现有对舟曲泥石流研究成果,分析了舟曲三眼峪沟所处的环境及舟曲特大泥石流的特征,同时分析造成舟曲特大泥石流的成因,知舟曲县城位于沟口冲洪积扇上,,另基于模糊综合评判法对舟曲泥石流危险性进行分析评价,在此基础上结合舟曲泥石流灾害的实际,提出了适宜的泥石流灾害防治对策。

Debris flow is mon natural disasters taking place in a mountainous area, it posed of soil, rock and other solid material and water under the action of gravity along the steep slope movement of fluid saturated, the sudden, shorter duration, but the disaster is very serious, sometimes even devastating. In August 7, 2010 Gansu Zhouqu especially big flush flood and debris flow disaster caused by catastrophic, casualties number, property loss in the history of our country have since recorded most of the debris flow disaster. The author of this article through access to a large number of documents and the existing research results of debris flow in Zhouqu, analysed Zhouqu three eye Valley located environment and Zhouqu large debris flow characteristics, at the same time analysis of the causes of Zhouqu large debris flow formation, Zhouqu county is located at alluvial fan, Zhouqu debris flow losses is one of the reasons, the other based on prehensive evaluation method to the Zhouqu debris flow hazard analysis and evaluation, on the basis of bination of debris flow disaster in Zhouqu is actual, put forward appropriate disaster prevention countermeasures.
Key word: Zhouqu Large debris flow Cause analysis of prehensive evaluation method Prevention and control measures
