AUTOMATIC MONITORING OF MADALING GEOLOGICAL DISASTER ON DUYUN,GUIZHOU PROVINCE
摘要
Abstract
Small collapses had happened intermittently at Madaling,Duyun in Guizhou province since 2003.A large-scale landslide happened on May 18th,2006 due to continuous rainfall.The debris,caused by slump-mass, rolled by the water released from gob,scraped the residual slope wash of the gull,which forms the mud-rock flow. Such kind of geo-hazard,presenting as chain reaction,is composed of the collapse,landslide and secondary flow, and forms a disaster chain of collapse landslide and debris flow.This paper takes this Madaling geological disaster chain as the study object.It is based on the regional environmental geological survey and research of regularity of geological disaster chain.It takes rainfall,relative displacement,obliquity,osmotic pressure water head,mud level,infrasound as the monitoring indexes.Automatic monitoring stations are set up at trailing edge of collapse body and mouth of debris flow.It forms an automatic monitoring system by integrating automatic collection,wireless transmission,data gathering and analysis,decision-making and early warning.Indicated from the running state of monitoring system and monitoring results,it can reflect the deformation behavior of geological disaster chain better by live transmission of monitoring data,offer technical assistance for early warning of the disaster chain.关键词
