高铁控制网复测数据处理与控制点稳定性分析

Data Processing and Stability Analysis of Control Network Resurveying in High-Speed Railway

介绍了汉十高铁控制网复测方案,结合复测技术及评判标准阐述了控制网复测数据处理流程,详细分析了控制点的稳定性,最终得到复测坐标成果,同时对原测成果进行了更新。

In this paper, the technical plan of the control network resurveying on Han-Shi high-speed railway is firstly introduced.Then the specific flow of thedata processing and the quality evaluation of the resurveying results are elaborated,especially the evaluation principles of the stability analysis of control points. As a consequence,the stability of the control network is analyzed according to the resurveying requirements,with the goal of finding out the unstable points whose coordinates should be recalculated and amended and getting the coordinates of the control network points updated.
