摘　　要：铁路隧道通风方式选择及通风效果关系到隧道的施工进度、施工作业人员身体健康、工程施工造价等方面。单线铁路隧道断面狭小,尤其对于设置大坡度斜井辅助坑道的长距离独头掘进施工期间通风极为困难,以衢宁铁路(福建段)站前I标仙岩隧道斜井工区大里程工点通风进行方案研究,并对关键技术与管理措施进行总结归纳,可为类似工程提供相应的施工参考。The choice of ventilation mode and ventilation effect of railway tunnels are related to the construction progress of tunnels,the health of construction workers,and the construction cost. The section of the single-track railway tunnel is narrow, especially for the long-distance single head excavation during the construction of the auxiliary slope of the steep slope. It is extremely difficult to ventilate the large-scale work site in the inclined shaft of the I-mark Xianyan tunnel in front of the Suining Railway (Fujian section). Conduct program research,summarize and summarize key technologies and management measures,and provide corresponding construction references for similar projects in the future.
