The Engineering Application of Displacement Monitoring in High and Steep Slope by GPS

Introductions of GPS(Global Positioning System) are made.The introduction consists of the main structure of auto displacement monitoring system,the theory of displacement monitoring and the method to improve the accuracy of observation.Furthermore,GPS is applied in one high mine slope for the displacement monitoring,which consist of the monitoring system,monitoring mode and monitoring steps.At last,the analysis of monitoring results shows that GPS technique has very high precision.In the engineering applications,it is not restricted by the weather conditions as well as its high degree of automation.The potential failure place of slope and the failure time can be predicted by the displacement monitoring of GPS,and the data provided by GPS show that the deformation velocity of slope is 0.247-0.560 mm/d,which is under the safety limit extension 10.0-20.0 mm/d,so this slope is in the stable state,and the safety of production is guaranteed by the application of GPS.
