摘要
随着铁路领域发展及地质条件变化,既有铁路线路无法满足运营要求,需对部分病害铁路隧道进行改建施工。既有新渔坝隧道属病害隧道,为确保铁路运营安全,对既有新渔坝隧道改扩建施工。改建六台山隧道施工地质条件差、埋深浅、既有线干扰大等影响,施工工期紧,难度大。为顺利完成改建工程施工,根据现场实际情况,优化施工方案。
With the development of the railway field and changes in geological conditions, existing railway lines cannot meet operational requirements, and some diseased railway tunnels need to be rebuilt. The existing Xinyuba tunnel is a diseased tunnel. In order to ensure the safety of railway operation, the existing Xinyuba tunnel was rebuilt and expanded. The construction of the Liutaishan tunnel has poor construction geological conditions, shallow burial depth and large interference from existing lines, and the construction period is tight and difficult. In order to successfully complete the reconstruction project, it optimizes the construction plan according to the actual situation on site.
