    GPS自动化监测技术在接娘坪变形体中的应用

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

    • 摘要: 接娘坪变形体位于贵州省都匀市,鉴于该地区的严重变形和可能失稳造成的严重后果,决定对该地区的变形进行监测。通过对该类型变形体监测预警指标的探讨,结合国内相关项目的经验和该地区的地形地貌等条件,选择了基于GPS的自动化监测技术,并辅以表面裂缝监测和降雨量监测。通过对该项目的建设,介绍了自动监测系统的组成与设计,并对一机多天线的技术进行了明确的阐述。通过表面裂缝和表面位移监测数据的对比,在一定程度上进一步印证了GPS在该项目的适用性。自2013年3月至今,该系统的监测结果显示监测点累计变形和沉降量最大的点都位于G2号监测站上,且4个监测点的平面变形方向都向煤矿集中开采的南西向,这反映了该坡体的变形主要是与山体下部煤矿开采有关,与当地降雨量的关系不明显。

       

      Abstract: 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.
