摘要
针对大坝、矿山等大型工程在开挖过程中形成的高危边坡的形变监测，提出GPS一机多天线方法，建立了远程自动化边坡形变监测系统。详细分析了GPS／GPRS无线数据传输和微型低噪声放大器开发等关键技术。该系统已应用到小湾水电站的高边坡形变监测。一年多的连续监测结果表明，系统运行稳定可靠，水平方向定位精度达2—3mm，垂直方向定位精度达5-6mm。
A new method based on GPS with multi-antenna system （GMAS） for monitoring the deformation of high-risk rocky slopes or large scale engineering structures was developed and a remote automatic monitoring system was established. The principles of the electronic switching device for GMAS and GPRS wireless data transmission and the micro-amplifier were presented. The proposed system was used to monitor the deformation of the steep rocky slope in the Xiaowan Hydro Project. The observation data show that the system works well, the horizontal positioning accuracy is about 2 - 3 mm and vertical positioning accuracy is about 5 - 6mm.
