沪杭铁路下浅埋公路隧道施工技术

Construction Technology for the Shallow-buried Highway Tunnel Crossing the Hu-Hang Railway Underneath

解放路延伸工程的解放路隧道穿越沪杭铁路,沪杭铁路为国家铁路主干线,行车密度很大,为确保解放路隧道施工时沪杭铁路的运输安全畅通,尽量减少隧道施工对铁路行车的影响,保证隧道的安全施工,介绍饱和砂质粉土地层邻河超浅埋隧道下穿既有沪杭铁路的施工技术,包括隧道开挖、衬砌、支护等过程中所采取的一系列施工措施,保证了工程的顺利实施。

The Jiefang Road Tunnel of the Jiefang-Road-extending Project has to cross the Hu-Hang Railway underneath, which is one of the national trunk railways of China with busy traffic. In order to ensure the safe and normal operation of the Hu-Hang Railway during the construction of the Jiefang Road tunnel, a series of countermeasures are taken to minimize the impact of the tunnel construction on the railway operation and to ensure the safety of the tunnel construction. Those techniques adopted for the project make the project under way with great success. The article presents a description of the construction technology for the shallow-buried river-neighboring tunnel crossing the Hu-Hang Railway underneath in saturated sandy silt ground.
