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 is taken as the research object, implements rainfall, surface displacement, fracture displacement and deep displacement monitoring, takes the lead in carrying out real-time automated professional monitoring of landslides in Xining City, and builds 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.
