摘　　要：以东非肯尼亚恩贡山单线长隧道施工为依托,对隧道断面尺寸和施工作业空间进行统计分析,对比不同设备选型条件下的施工进度指标和经济指标,确定了单线铁路隧道相对合理的设备选型方案;通过扩大避车洞室,设计洞内交通运输,合理安排工序,实现了单线隧道快速施工。研究结果表明,分析不同设备选型的经济效益、工期影响、效率冗余和技术条件等,合理设计交通组织,是实现单线铁路隧道快速施工的关键。This article is based on the construction of the single-track long tunnel in Mount Ngong,Kenya,East Africa.Through statistical analysis of tunnel section size and construction space conditions and comparison of construction progress indicators and economic indicators under different equipment selection conditions,this paper determines the relatively reasonable single-line tunnel equipment selection scheme.The rapid construction of a single-track tunnel has been achieved by expanding the shelter,designing transportation within the tunnel,and arranging procedures reasonably.The research results show that the analysis of economic benefits of different equipment selection,duration impact,efficiency redundancy,technical conditions and reasonable design of traffic organization are the key to realize the rapid construction of single track railway tunnel.
