在铁路隧道施工中,隧道的开挖与支护是施工质量及安全控制的关键环节。本文浅论了铁路隧道CRD法及CD法开挖与支护施工技术。本文特别点在于隧道受到车站布局限制,三线车站伸入隧道进口内,由进口三线大跨度开挖与支护163m渐变为单线。
In the construction of railway tunnels, the excavation and support of the tunnels are the key aspects of construction quality and safety control. This article discusses the CRD method and CD method of railway tunnel excavation and support construction technology. The special point of this paper is that the tunnel is limited by the layout of the station. The third-line station extends into the entrance of the tunnel and is transformed into a single lane by the large-span excavation and support of the imported three lines of 163m.
