    APPLICATION OF GPS AUTO-MONITORING TECHNOLOGY TO DEFORMATION BODY OF JIENIANGPING

    • The Jieniangping deformation body lies in the city of Duyun,Guizhou province. Considering the severe deformation and potential consequences caused by instability,we decided to monitor the deformation at this site. We based on the type of deformation monitoring and early warning index,and connected them with the domestic related project experience and landform condition in the region. We chose the GPS based automatic monitoring technology,and supplemented it with surface crack monitoring and rainfall monitoring. The structure and the design of automatic monitoring system is introduced in this paper. The multi-antenna technology is clearly described. We compared the GPS data with the surface crack and surface displacement monitoring data. To some extent,we further verified the applicability of GPS in the project. Since March 2013,the monitoring results of the system show that the largest monitoring point of the accumulative deformation and subsidence is located at G2. In addition,the direction of deformation of four monitoring concentrations in coal mining in the southwest,reflecting the deformation of slope is mainly related to the mountain bottom coal mining. The relationship between deformation and local rainfall is not obvious.
