采用护拱法处理隧道塌方的具体运用实例

Example of the application of arch protection method in collapse treatment of tunnel

结合襄渝二线新冷水隧道工程实例,分析了隧道塌方的原因,提出了隧道塌方治理方案,重点介绍了护拱法的施工过程及施工安全措施,得出了护拱法抗冲击防护性能优于费用相当的其他支护方案的结论。

Combined with Xinlengshui tunnel work in the double line engineering of Xiang-Yu railway line reasons caused the tunnel collapse are analyzed; at the same time corresponding treatment scheme is proposed. According to the application of arch protection method practical construction process and safety measures are mainly introduced. Practice shows arch protection method is superior to other supporting schemes with gocyl shock resistance and protection performances.
