摘　　要： 2013年4月20日四川省芦山7.0级地震,宝兴县城距离震中仅15km,县城的烈度为Ⅶ度,致使县城周边诱发大量地质灾害,严重威胁县城的安全。以冷木沟泥石流为例,根据泥石流的形成条件、诱发因素、启动机理、运动特点和发展趋势,采用降雨量、地声、泥水位、断线、视频、防灾报警仪和信息化管理系统等多种手段,通过在形成区和流通区部署4套视频、3套自动雨量计、2套泥水位、2套地声和1套防灾警报仪,实现地表与地下、野外与室内、自动化与人工、数据与视频、硬件与软件、直接与间接等多种监测手段相结合,建立冷木沟泥石流灾害监测预警系统,以达到全方位、多层次、全天候的监测目的。 Lushan Ms7.0earthquake occurred in Sichuan Province on April 20,2013.The county seat of Baoxing is away from the epicenter only 15km.The earthquake intensity degree isⅦin the county seat.It has triggered a large number of geological disasters around the county,and threated the safety of the county seriously.In this paper,taking the debris flow in Lengmu gully as the example,according to the formation conditions of debris flow,predisposing factors,initiation mechanism,motion characteristics and trends,using rainfall,the ground sound,water level,line-break,video,disaster alarm apparatus and information management systems and other means,by arranging 4sets of video,3sets of automatic rain gauges,2sets of mud water level monitors,2sets of underground sound monitors and a set of disaster warning device between forming region and circulation region,we achieve many monitoring devices combination of ground surface and underground,outdoor and indoor,automation and manual work,data and video,hardware and software,direct and indirect.Debris flow monitoring and warning system is established in Lengmu gully in order to realize all-round,multi-level,all-weather monitoring purpose.
