城市轨道交通工程控制测量建网策略

为了解决城市轨道交通大规模、大范围建设过程中导致的测量控制网的整体性差、新旧坐标系统不匹配等问题,分析了全国城市轨道交通工程建设的新趋势,根据工作经验,总结了目前城市轨道交通工程测量工作面临的新问题,有针对性地提出了城市轨道交通工程地面控制测量建网策略。实践证明,通过实施这些策略,能够很好地解决目前城市轨道交通建设所面临的诸多测量问题。

Strategies on Establishing of Control Survey Network of Urban Rail Transit Works

In the large-scale construction of urban rail transit works, the integrity of the control survey network is not so good and the new coordinate system can not match with the old one so well. The trend of the construction of urban rail transit works in China is analyzed, problems that may be encountered in the surveying of urban rail transit works are summarized, and strategies are recommended on the establishing of the ground surface control survey network of urban rail transit works. The practice shows that many problems encountered in the survey of urban rail transit works can be solved by adopting the strategies recommended.
