摘　　要：西秦岭特长隧道是目前中国铁路建设史上采用TBM掘进最长的隧道,设计为两座单线隧道,采用钻爆法和TBM相结合的施工方案进行施工。文章结合该隧道的环境及工程、水文地质情况,对方案比选及其TBM施工特点及工程适应性、隧道衬砌断面及其支护参数设计、TBM掘进与同步衬砌、连续皮带机出碴等关键技术方案进行了分析论述,并介绍了TBM设备和隧道的施工概况。The West Qinling extra-long tunnel, the longest TBM-driven tunnel in China＇s railway history, is a double-tube single-track tunnel being constructed using a combination of the drill and blast and TBM methods. Based on environmental and hydrogeological conditions, this paper analyzes： a construction scheme comparison; construction characteristics; the engineering adaptability of the TBM, the design of tunnel lining section and its support parameters; the synchronization of lining and TBM driving; and continuous conveyor belt mucking. It also introduces general information regarding the TBM equipment and tunnel construction.
