隧道进洞方法从刚开始的大开挖到如今的零开挖,在理念不断创新的同时施工技术也在不断进步。各种工法与辅助施工手段进行不同组合,就能适应不同的地质地形,实现快速、安全进洞。文章在总结不同隧道进洞方法的基础上,结合忻阜高速公路凤凰岭隧道进出口的地形地质情况,提出了凤凰岭隧道进口反压挡墙斜交直接进洞方案和出口双层小导管直接进洞方案,取得了很好的工程效果。 Tunneling methods from the beginning of the excavation to today’s zero excavation, the concept of continuous innovation at the same time construction technology is also continuous improvement. A variety of construction methods and auxiliary construction methods for different combinations, will be able to adapt to different geological topography, to achieve rapid and safe hole. On the basis of summarizing the tunneling methods of different tunnels and combining with the topography and geology of the Fenghueling tunnel of Xinfu Expressway, this paper puts forward the scheme of direct hole injection with reverse pressure retaining wall in Fenghuangling Tunnel and the direct double outlet small double conduit Into the hole program, made a very good project results.
