Ⅴ级浅埋偏压隧道出洞方案

Ⅴ grade shallow burying bias-voltage tunnel unkennelling program

为了确保隧道后续施工的安全和洞口段初期支护质量,结合新五块石一号隧道工程概况,详细介绍了隧道出洞的施工方案,并就浅埋偏压隧道出洞时所遇见的一些问题做一探讨,提出了相应的解决措施,为类似隧道施工提供参考。

To assure the safety of tunnel succeeding construction and the quality of opening original supporting and combined with the new five stones No. 1 tunnel project general situation, it specific introduces the tunnel unkennelling construction program, discusses the problems that happened in shallow burying bias-voltage tunnel unkennelling, and puts forward the corresponding solving steps, this supplies reference to the construction of similar tunnel.
