摘　　要：衢宁铁路(福建段)鹫峰山1号隧道为艰险山区单洞单线特长隧道,洞外大临布置艰巨,洞内独头掘进距离长达3596m,断面小,施工工序干扰大,运输组织难度大,快速掘进难度大,实现工期目标困难。文章以鹫峰山1号隧道施工为依托,对艰险山区单洞单线铁路如何优质快速掘进进行探究,主要从交通运输组织、风险管控、施工通风、地质预报、快速掘进方面进行分析总结,其成功经验望能为以后类似隧道施工起到一定的参考和借鉴作用。Jiufeng Mountain Tunnel No.1 of Quning Railway(Fujian Section)is a single-tunnel,single-track and extralong tunnel in difficult mountainous areas.It is difficult to arrange outside the tunnel.The single-headed excavation distance in the tunnel is 3 596 m,the section is small,the construction process is disturbed greatly,the transportation organization is difficult,and the fast excavation is difficult to achieve the target of the construction period.Based on the construction of Jiufeng Mountain Tunnel No.1,this paper probed into the high-quality and fast tunneling of single-tunnel single-track railway in difficult and dangerous mountainous areas,mainly from the aspects of transportation organization,risk management and control,construction ventilation,geological prediction and rapid tunneling,and its successful experience is expected to play a certain reference role for similar tunnel construction in the future.
