摘要
以城市地铁采用矿山法施工小间距隧道技术为研究目标,分析了地铁小间距隧道施工的技术难点和关键点,总结了地铁小间距隧道施工方法、技术思路和施工技术措施,介绍了广州地铁三号线岗石区间超小间距隧道工程实例。认为,地铁小间距隧道施工应采用综合性技术和措施,提高隧道支护结构的强度、刚度和整体性,减少和控制两条隧道开挖时的相互影响,合理地利用围岩自承能力,保证围岩与支护结构共同作用。
The construction technique for metro neighborhood tunnels is studied in the paper, with the engineering background of tunneling of Gangshi section of Guangzhou metro. The key points of the construction of metro neighborhood tunnels are analyzed. The excavation method, technological process, measures and the monitoring measurement for the tunneling of the small spacing tunnels are discussed. Three points are given for the construction of the metro neighborhood tunnels, first, comprehensive methods and measures; second, great strength, rigidity and multi-links between two tunnels structures; third, reduce and control the interaction during the excavation of two tunnels.
