城市CORS参考站稳定性监测与区域地表变形分析

摘要

It presents the data-processing strategies for CORS sites stability monitoring based on Changzhou Continuously Operating Reference Stations (CZCORS) data.Different terrestrial reference frames and monitoring datums are compared in the analysis which have different impacts on the CORS site displacement results.Based on the CZCORS data processing results,precise horizontal displacement field are established and vertical displacement patterns are also analysed.Some useful conclusions and suggestions are proposed in the end.%以常州市CZCORS监测网的数据处理为例,探讨城市CORS参考站稳定性监测的方法,对比分析不同参考框架和变形监测基准对计算参考站三维位移结果的影响.利用CZCORS监测成果,建立精确的城市水平位移速度场,并对区域地表垂直位移变化规律进行分析,给出一些有益的结论和建议.
