摘要
以广州新光大桥为研究对象,对其变形监测控制网的布设进行试验研究,包括桥梁高程监测控制网测量的方法和精度分析、桥梁平面监测控制网测量的方法和精度分析以及桥梁关键监测点位置布设研究。其中在高程监测控制网测量中,分别采用了跨河水准测量、测量机器人三角高程法测量、GPS测高3种方法进行比对实验;在平面监测控制网测量中则采用高精度测量机器人和GPS两种方法进行比对实验。由试验结果,得出结论,为同类项目的开展提供有益的借鉴。
The paper takes Guangzhou Xinguang bridge for example to study the surveying method and accuracy analysis of control network measure with oversize bridges,concerning both elevation and flat panel monitoring networks.Besides,we also in detail describe how to determine the key sites of oversize bridge itself for further GPS deformation monitoring system design,which can provide valuable reference for similar projects.
