摘要
位于福建省京福高速公路上的金旗山隧道是一座典型的双线双洞、小净距公路隧道 ,其双洞中心线间距为 17.5 19m。文章以该隧道为例 ,介绍小净距隧道的洞身开挖和施工顺序以及中夹岩柱加固、锚喷支护、监控量测等关键工序的施工方法和技术要点 。
Jinqishan tunnel on Jingfu expressway is a typical double lane twin bore highway tunnel with small spacing, the spacing between the center lines of two tunnels being 17.519m. In this paper the technical keys of excavation sequence, reinforcement of the intermediate rock pillar, supporting with anchor and shotcrete as well as monitoring measurements are presented by taking Jinqishan tunnel for example, which enriches the experience for the design and construction of small spaced tunnels.
