摘要
隧道穿过软弱围岩时,超前支护中的超长超前导管是一种较特殊的施工措施。结合达陕高速公路金竹山隧道该施工技术的应用,重点对超长超前导管技术进行分析和探讨,以供同类工程借鉴和参考。
Ultra-long advancing conduit is a special construction measure in forepoling when crossing weak surrounding rock for tunnel.Combined the application of construction technology of Jinzhushan tunnel of Dazhou City to Shaanxi Expressway,this paper focused on the analysis and discussion of ultra-long advancing conduit technology,providing reference for similar projects.
