西宁市特大滑坡监测预警示范

Monitoring and Early Warning Demonstration of Huge Landslide in Xining City

滑坡是西宁市主要的地质灾害类型,对当地人民群众生命财产安全危害严重,传统的监测方法以人工巡查为主,无法做到监测数据实时传输,远不能满足新形势下地质灾害防治工作的需求。以张家湾特大型滑坡为研究对象,实施了雨量、地表位移、裂缝位移及深部位移监测,率先在西宁市开展了滑坡实时自动化专业监测,通过对获取的监测数据分析,建成西宁市特大型滑坡监测预警示范工程,为实时掌握地质灾害变形规律、险情预报、灾害防治及政府防灾减灾决策提供技术支撑。

Landslides are the main type of geological hazards in Xining city,and they are a serious hazard to the lives and properties of local people.Traditional monitoring methods are based on manual inspections,which cannot achieve real-time transmission of monitoring data and are far from meeting the needs of geological hazard prevention and control work under the new situation.Zhangjiawan huge landslide was taken as the research object,implements rainfall,surface displacement,fracture displacement and deep displacement monitoring,took the lead in carrying out real-time automated professional monitoring of landslides in Xining City,and built a demonstration project for monitoring and early warning of huge landslides in Xining city by analyzing the acquired monitoring data.It provides technical support for the real-time control of geological disaster deformation law,hazard prediction,disaster prevention and control and government disaster prevention and mitigation decision.
