变形监测网合适参考系的确定与稳定性分析

摘要

This paper proposes a method and flow for data processing and stability analysis of deformation monitoring network based on the rank defect free network adjustment.The strategy can resolve the confirmation of robust iterative weights during several periods of observation.Then,analyzes the point＇s stability of the network by the method of mean gap,which is proved practically and can reflect stability of deformation monitoring network correctly through the computational example.%基于秩亏自由网平差原理,提出了一套变形监测网数据处理与稳定性分析的理论与流程,解决了多期观测数据参考系稳定权阵的确定问题,利用平均间隙法原理,对监测网点进行了稳定性分析。通过计算实例说明了其可行性。
