摘要
泥石流是一种常见的山地灾害,具有发生突然、历时短暂、来势凶猛和破坏力强等特点。沟谷型泥石流由上而下可分为形成区、流通区和堆积区3个区段。基于泥石流产生、运动、危害的各个阶段的特点,采用雨量遥测、地声遥测、泥位遥测以及有线泥位、冲击力和摄像监测等子系统和综控中心组成泥石流自动化监测系统。系统的各监测站均可自带动力和自动控制,仪器设备集成度高,便于进行各种工况下的野外监测。系统可以快速、准确地监测泥石流灾害,有效降低泥石流的危害性。
Debris flow is a common geo-hazard,with characteristic of suddeness,short duration,ferocious power and strong destruction and so on.From top-down,the gully debris flow can be divided into formation zone,circulation zone and accumulation zone.Based on the characteristics in occurring stage,movement stage and damage stage,a debris flow automatic monitoring system was composed of several subsystems and an integrated control center.The subsystems included rainfall telemetry,ground acoustic telemetry,mud-position telemetry,wired mud-location,impact force and camera monitoring.Each monitoring station of the system was equipped with power and automatic control.The aparatus has a high integrated level,which is easy to carry out field monitoring under various conditions.The system can monitor the debris flow quickly and accurately so as to reduce the damage of debris flow
