摘　　要：铺轨施工测量和轨道精调测量作业是提升轨道平整度和平顺性的重要工作,文中针对传统轨道精调作业效率低、精调数据不宜留存等问题,以北京大兴机场线快速轨道交通工程项目为例,探讨了轨道几何状态测量仪在数据采集、内业处理和作业过程中需要注意的事项,最终为满足列车设计时速提供技术保障。最后研究与总结出一套适用于城市快速轨道交通工程的轨道测量精调技术。Track laying construction measurement and track precision adjustment measurement are important tasks for improving track flatness and smoothness.This article addresses the issues of low efficiency and inappropriate re⁃tention of precision adjustment data in traditional track precision adjustment operations.Taking the Beijing Daxing Airport Line Rapid Rail Transit Project as the case,it discusses the precautions that need to be taken for track geo⁃metric state measurement instruments in data collection,office processing,and operation processes.Technical sup⁃ports are provided to meet the design speed of the train.Finally,a set of precise track measurement and adjustment techniques suitable for urban rapid rail transit engineering is studied and summarized.
