CORS数据的地面变形和参考站稳定性分析

Analysis strategy of ground deformation and stability of reference stations using CORS data

针对目前利用CORS观测数据进行地面变形和参考站点位稳定性分析时缺乏具有较好通用性的数据处理与分析一般流程和策略的问题,该文在对地面变形和参考站点位稳定性分析需要考虑的影响因素进行分析的基础上,提出了一种数据处理与分析的一般流程和策略,并针对大范围地面变形(或地壳板块运动)分析与小范围(局部)地面变形分析以及CORS参考站点位稳定性分析的不同特点,提出了相应的变形分析基准的合理选择与统一方法。实验结果表明:所提出的流程、策略以及基准选择与统一方法能够获得精确、可靠的地面变形和参考站点位稳定性分析成果。

Aiming at the problem that the process of analyzing surface deformation and the stability of reference stations using CORS data is usually lack of general flow and strategy with good universality currently, the paper proposed a strategy for the data processing and analysis through studying on the influential factors of surface deformation and the stability of reference stations. In addition, aiming at the different characteristics of the large scale ground deformation （or crustal plate movement） analysis and small scale （local） surface deformation analysis as well as the stability analysis of CORS reference stations, the corresponding and reasonable method to choice and unify the datum of deformation analysis were put forward. Experimental result showed that the proposed methodology could help obtain the accurate and reliable analytic achievement of ground deformation and the stability of reference stations.
