高速铁路CPⅢ轨道控制网为轨道铺设和后续运营维护提供了控制基准,需要定期对其进行复测。相对CPⅢ高程网复测,高速铁路CPⅢ平面网复测难度更大,需要注意的环节更多。文章结合笔者参与的国内多条高速铁路CPⅢ平面网复测的实践经验,通过对CPⅢ平面网复测过程中出现的若干突出问题和关键环节(如已知点联测方式、全站仪及棱镜检测、已知点兼容性检查、CPⅢ成果更新、超限点二次检测等)进行逐一、详细地分析和探讨,并给出具体的解决方法和实施应用标准,从而为今后高速铁路CPⅢ轨道控制网复测工作的顺利开展提供宝贵的经验和正确的思路,也对今后完善现有测量规范具有重要的参考意义和实用价值。
高速鐵路CPⅢ軌道控製網為軌道鋪設和後續運營維護提供瞭控製基準,需要定期對其進行複測。相對CPⅢ高程網複測,高速鐵路CPⅢ平麵網複測難度更大,需要註意的環節更多。文章結閤筆者參與的國內多條高速鐵路CPⅢ平麵網複測的實踐經驗,通過對CPⅢ平麵網複測過程中齣現的若榦突齣問題和關鍵環節(如已知點聯測方式、全站儀及稜鏡檢測、已知點兼容性檢查、CPⅢ成果更新、超限點二次檢測等)進行逐一、詳細地分析和探討,併給齣具體的解決方法和實施應用標準,從而為今後高速鐵路CPⅢ軌道控製網複測工作的順利開展提供寶貴的經驗和正確的思路,也對今後完善現有測量規範具有重要的參攷意義和實用價值。

The track control network (CPⅢ)of high-speed railway provides control datum for track laying,subsequent operation and maintenance.It is necessary to resurvey CPⅢperiodically.The CPⅢhorizontal repetitive survey is rela-tively more difficult than vertical repetitive survey and has more workload to be done.Combined with practical experi-ences of CPⅢ horizontal repetitive survey of high-speed railways in China,in the paper a discussion has been made on the main problems and key points during CPⅢ horizontal repetitive survey one by one in detail.Then specific solution and implementation standards have been presented finally,which will provide valuable experiences and proper ideas for CPⅢ track control network repetitive survey of high-speed railway and also a good reference for improving the existing survey specifications in the future.
