Abstract: 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.
