本文以广州地铁五号线区庄-杨箕区间重叠隧道盾构法施工为背景,通过计算分析得出的理论结果来指导施工,确定采用先下洞后上洞的施工顺序,并取得了成功。为今后类似工程的施工与设计提供参考。
In this paper, based on the construction of overlapping tunnel shield tunneling method in Guangzhou Zhuangzi Subway Line-Yangji Interval, the theoretical results obtained through the calculation and analysis are used to guide the construction and to determine the construction sequence of the tunnel after the first cave-down and the success . It will provide references for the construction and design of similar projects in the future.
