摘　　要：随着国家经济和铁路建设的发展,隧道工程在铁路建设中占比越来越大。然而,受地质水文、地理位置等因素影响,隧道工程施工面临较大的困难。基于此,以福州某货运铁路隧道工程为例,探讨隧道浅埋暗挖工程施工技术。对隧道浅埋段开挖支护过程中存在的风险与对策进行分析,并提出该铁路隧道浅埋暗挖施工工序控制要点,可以提高铁路隧道工程整体的施工功效和质量,同时希望可以为类似浅埋暗挖隧道工程提供经验参考。With the development of national economy and railway construction,tunnel engineering accounts for more and more important proportion of railway construction.However,railway tunnel engineering brings great difficulties to tunnel engineering due to the influence of geology,hydrology,geographical location and other factors.Based on this,this paper takes a freight railway tunnel project in Fuzhou as an example to discuss the construction technology of shallow excavation in tunnels.It analyzes the risks and countermeasures existing in the excavation and support process of shallow buried tunnel section,and puts forward the control points of the shallow excavation construction process of the railway tunnel,which can improve the overall construction efficiency and quality of the railway tunnel project,and hopes to provide an empirical reference for similar shallow excavation tunnel projects.
