摘　　要：城市轨道交通工程地下隧道空间有限,曲线段较多且存在半径较小的曲线,通视条件差,为提高其铺轨精度及效率,减少后期运营列车对轨道的磨损,提高乘坐的舒适性。本文引进高铁基桩控制网(CPIII)技术应用到城市轨道交通铺轨控制网,讨论了任意设站控制网的布设、纵向布点间距的要求及任意设站控制网的测量及数据处理。以郑州市轨道交通4号线为例进行任意设站控制的测量,验证了任意设站控制网在地铁轨道控制网的精度满足铺轨的要求。The underground tunnel space of urban rail transit project is limited,there are many curve sections with small radius,and the intervisibility conditions are poor.In order to improve the accuracy and efficiency of track laying,reduce the wear of track by later operating trains,and improve the ride comfort.In this paper,the high-speed railway CPIII technology was introduced and applied to the track laying control network of urban rail transit.The layout of arbitrary station control network,the requirements of longitudinal point spacing,and the measurement and data processing of arbitrary station control network were discussed.Taking Zhengzhou rail transit line 4 as an example,the measurement of arbitrary station control network verified that the accuracy of arbitrary station control network in metro rail control network could meet the requirements of track laying.
