摘　　要：高精度施工测量基准是轨道交通高质量建设的重要前提,具有"保存要求高、精度要求高、兼容性要求高"的特点。为确保轨道交通线路互联互通建设和保障施工安全,本文基于"整网设计、连片解算、兼容共用"的思路,综合采用GNSS、测量机器人等多种手段提出"大规模、多线路、不同期"GNSS控制网融合与衔接方案,对类似项目具有参考意义。High-precision construction survey benchmark is an important prerequisite for high-quality construction of rail transit.It has the characteristics of high preservation,high precision and high compatibility requirement.In order to ensure the interconnection of rail transit lines and the safety of construction,based on the idea of“whole network design,joint solution,compatibility and sharing”,this paper uses GNSS,surveying robot and other means to provide a scheme of“large-scale,multi-line,different period”GNSS control network integration and connection.It has reference significance for similar projects.
