浅谈小净距浅埋偏压富水段隧道施工技术

Discussion on Tunnel Construction Technology of Shallow-buried Unsymmetrical-pressure Water-rich Section with Small Clear Distance

文章结合靖西至龙邦高速公路龙邦隧道工程实例,对小净距浅埋偏压富水隧道施工技术进行研究,从地表冲沟处理、超前地质预报、洞身开挖、复合式衬砌支护及监控量测等施工环节,介绍了小净距浅埋偏压富水隧道的施工方案。

Based on the engineering example of Longbang Tunnel in Jingxi-Longbang Expressway,this article discussed the construction technology of shallow-buried unsymmetrical-pressure water-rich tunnels with small clear distance,and introduced the construction scheme of shallow-buried unsymmetrical-pressure water-rich tunnels with small clear distance from the construction links such as ground-surface gully treatment,advanced geological prediction,cave excavation,compound lining support and monitoring measurement.
