摘要
依据广州市轨道交通2025年建设规划线路平面控制测量的技术要求,本文详细介绍了广州轨道交通规划线路框架网的设计、外业观测和数据处理方法,并分析了该平面控制网的精度,总结了城市轨道交通线路平面控制网测量的技术要点,对大型轨道交通控制网测量布设具有一定的借鉴作用。
Considering the technique requirements for horizontal control survey of Guangzhou metro in 2025 construction planning lines, this paper introduces the network design, field observation and data processing of this GNSS horizontal control network. Moreover, the accuracy of this GNSS control network is analyzed in detail. Based on this GNSS horizontal control network, the key technique requirements and some useful suggestions are put forward for the GNSS horizontal control surveying of the planning urban rail transit lines.
