摘要
GPS定位技术的发展为边坡变形监测提供了一种简便可靠的手段。本文阐述了应用GPS技术提取地表变形信息和GPS数据处理的方法,结合重庆市万州区明镜滩应用GPS监测网进行滑坡监测的实践,研究了在地形复杂、观测条件恶劣的山区进行GPS滑坡变形监测点位选择、监测网布设和数据处理的方法。监测结果表明,GPS变形监测的精度可达到亚厘米级,完全可以应用于滑坡变形监测。
The development of GPS positioning technique has provided a simple and reliable way ot slope detormatlon monitoring. In this paper, a GPS-based data processing and deformation information acquiring method is discussed. Combining the practice which using GPS monitoring network for slope deformation monitoring in Ming Jingtan, Wanzhou, Chongqing, the author investigates a way of choosing GPS monitoring point, laying monitoring network, and data processing in the mountainous area where survey is discommodious. The result of monitoring shows that GPS deformation monitoring can reach an accuracy of millimeter scale and can meet demands of slope deformation monitoring.
