京津城际轨道设标网高程测量

The measurement accuracy analysis of track level surveying for Jingjin high-speed railway

针对高速铁路轨道设标网高程测量精度要求高、点位分布密集的特点,提出了Z字型观测路线方案,为提高测量精度从测站、测段,测量环境等方面提出了质量控制方案。京津城际高速铁路实测结果表明,本文提出的方法合理有效,满足无碴轨道铺轨和检验精度要求,达到了预期目的。

Duty control point coarctation and high measrment accuracy is demand for base-line control network,the Z model level route is popused in this paper,and some program for achieving accuracy surveying result such as quality control checking for surveying station,using especial foot plate are put forward.The Jingjin hailway surveying practise showed the effective methods and the scheme is satisfied the demand of track pavement and accuracy adjustment.And the goal is achieved.
