中文摘要：

从冰湖溃决型泥石流坝的形成、溃决机制,主要特点和成灾过程着手,在广泛收集和分析国内外有关冰川-冰湖-冰湖溃决-冰湖溃决泥石流-冰湖溃决泥石流坝-坝溃决研究基础上,通过川藏公路然乌至培龙段冰湖、冰湖溃决泥石流的区域考察,选择典型沟道米堆沟和光谢错冰湖典型点进行详勘,按照溃决泥石流重点防治溃决的主要原则,提出研究路段典型冰湖溃决泥石流预警的基本体系和配套技术。

英文摘要：

Based on the formation of debris-flow dam,outburst mechanism,the main features and disaster process,we chose the high way from Ranwu to Peilong in Tibet to be study area.The Guangxieco Lake is a typical outburst lake,and Midui Gully is its downstream gully.The region was investigated many times and chose to be the early-warning point.In this paper,an early warning system and supporting technology for debris flow caused by glacier lake outburst is proposed depending on the main principle of glacier-lake outburst prevention.
