Application of GPS Technology for Landslide Monitoring Sites in Xinjian of Ahai Reservoir Area

The development of GPS technology has provided a simple and reliable way of landslide deformation monitoring. Combining the practice of Xinjian landslide deformation monitoring which using GPS technology in Ahai reservoir area, the authors introduce the entire process of GPS deformation monitoring in mountainous area with complex terrain where survey condition is harsh. The main content of this paper includes the choice of GPS monitoring point, the design of monitoring network, field survey, data processing and deformation analysis etc. The results indicate that GPS deformation monitoring can reach an accuracy of millimeter scale, and this method is better than the traditional one in the requirements of high-precision deformation aspects of precision, speed, efficiency and benefit,fully meets monitoring.
