GPS PPP技术用于滑坡监测的试验与结果分析
Experiment results and analysis of landslide monitoring by using GPS PPP technology
摘要
Abstract
In order to study the precision and reliability, when the global positioning system (GPS) precise point positioning (PPP) technology is used to monitor the deformation of landslide or other geological hazards, some monitoring points are set on the landslide body and GPS PPP technology is used to monitor the landslide with real-time combined a big physical model experiment of a kind of landslide. Through the processing and analysis of monitoring data of the landslide from stable condition, start sliding to breaking down, the monitoring results of GPS PPP, GPS single epoch differential positioning and carrier wave phase real-time kinematic positioning are contrasted. The results show that the internal accordant accuracy of GPS PPP technology can achieve about 10 mm and the external accordant accuracy can achieve about 40 mm. And GPS PPP technology also has some superiority which the differential GPS does not have, such as without base-station, low cost, high efficiency and can obtain the absolute coordinates of monitoring points under the international terrestrial reference frame. The GPS PPP technology can be used to monitor and forecast the dynamic deformation of landslide and other geological hazards.关键词
