摘　　要：厦门市机场路一期工程梧村山隧道下穿浦南段是国内罕见的下穿密集建筑群的城市浅埋大跨连拱隧道。以下穿34号房屋为对象,详细介绍了房屋基础的注浆加固和抬升、无中墙连拱隧道结构、连拱隧道的CRD施工法、双层初期支护、地下长管棚、以及施工中的监控量测等工程措施在保证连拱隧道顺利穿越中的运用。The undercrossing Punan Section in Wucunshan Tunnel in Ximen Airport Expressway Project Phase I is an urban shallow large-span twin-arch tunnel undercrossing dense buildings being unusual at home. Based on undercrossed No.34 building as an object, this paper in detail introduces the utilizations of engineering measures such as grouting reinforcement and lifting of building foundation, twin-arch tunnel without mid-wall structure, CRD construction method for twin-arch tunnel, initial double-layer supporting, underground long pipe roof and supervisory measurements during construction, etc. for guaranteeing smooth undercrossing of the twin-arch tunnel.
