摘要
2011年7月3日,汶川县高家沟发生泥石流活动,泥石流堵塞岷江,造成重大损失。本文根据现场调查,对高家沟泥石流形成条件进行了分析,并重点分析了"堵溃"型高位泥石流的形成过程、启动机理及其运动特征,为该类泥石流的预防和治理提供了参考依据。
On July 3, 2011, Gaojia Gully in Wenchuan County occurred debris flow activity,which blocked Minjiang River and caused heavy losses. According to field investigation, this article analyses the formation conditions of this debris flow, and explores the formation process,initiation mechanism and movement characteristics of ＂block-burst＂ type of high-order debris flow particularly. And this paper this kind of debris flow. does some references for the prevention and governance of
