摘要
指出平面控制测量是地铁施工测量中一项关键性的工作,是实现施工横向贯通控制的关键,简要论述了施工段范围未达到《规范》限定精密导线布设基本要求时,如何进行施工首级平面控制测量布设及精度分析,以使之满足各阶段施工放样及最终贯通精度要求。
This paper holds that plane control survey is the critical link in subway construction survey and is the key to realize the construction lateral link-up. Afterwards, it discusses how to carry on first-level plane survey layout and precision analysis when the construction section scope doesn＇ t reach the limited precise wire layout requirements of the Norms, with a view to meet the construction layout at each construction phase and finial link-up precision requirements.
