摘要

研究目的：根据无砟轨道施工对平顺性要求，研究了为满足施工要求CPⅢ控制网的网形布设、施测方法。研究了为满足施工要求对CPⅢ控制网定位精度要求及CPⅢ控制网点位相对中误差及可重复测量误差精度控制指标，从而明确CPⅢ控制网点位的误差，最终为满足无砟轨道施工对平顺性要求提供测量保障。

研究结论：(1)CPⅢ控制网网形采用沿线路均匀布设、施测方法采用多方向后方交会，对于控制CPⅢ网点间相对中误差具有重要作用。(2)CPⅢ控制网点位相对中误差及可重复测量误差精度控制，能满足轨道施工高平顺度要求。

Abstract

Research purposes: According to the construction of Ballastless ride request，studying network layout and survey methods of CPⅢ control for meeting the construction requirements for．Studying to meet the construction requirements of the CPⅢ control network location accuracy requirements and CPⅢ Control Network relative error and repeatable measurement error precision control indicators，which explicitly CPⅢ Control Network error，and ultimately to meet the non—ballast track construction on the smoothness requirements Measurement of protection provided．

Research conclusions:：(1)CPⅢ control network is installed evenly along the railway and the multiple—direction intersection in rear is adopted in the measurement．This is crucial to control of the relative error between measurement spots of CPⅢ control network．(2)The relative error between measurement spots of CPⅢ Control Network and the repeatable precision control of the measurement error can meet meet the requirements of the track regularity．
