Study on Construction Treatment of Shallow Excavation of a Freight Railway Tunnel in Fuzhou
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.
