摘要
结合306国道经棚隧道施工实例,介绍了双侧壁导坑开挖、超前钢插板防护和大管棚做超前支护等大跨度风积砂隧道的施工方法及施工技术,为类似工程施工提供有益借鉴。
this article introduces the construction technology for long-span tunnels of aeolian sand, including the excavation of double-wall guide pit, the protection of preceding embedded steel board, the steel sheet pile preceding support and so on, which offers beneficial reference for similar works.
