摘要
岷江上游干旱河谷地区存在大量松散固体物质,泥石流给当地人民的生命财产带来了严重威胁。黑水县中芦花组垮沟泥石流为粘性泥石流,爆发泥石流的可能性极大,为该区域的典型泥石流之一。以芦花组垮沟泥石流为例分析了岷江上游干旱河谷地区泥石流发生的三个基本条件和促发(激发、触发和诱发)条件。通过对泥石流的形成条件分析,针对泥石流灾害的基本特征提出了相应的综合治理措施,对其治理效果进行了评述。为岷江上游地区的泥石流调查、勘察和评价提供了技术借鉴,也对相关工程研究具有一定的理论意义。
A lot of loose solid matter are in existence in the arid valley area of the upper reaches of the Minjiang River,and debris flow brings serious threat to the lives and property of the local people.The Kuagou debris flow in Heishui County is one of typical debris flows in the study area.The present paper has a discussion on three basic conditions and control of debris flow in the arid valley area of the upper reaches of the Minjiang River by the example of the Kuagou debris flow.
