特长隧道断层破碎带涌水治理研究

Research on Treatment of Water Gushing in Fault Fracture Zoneof Extra-long Tunnel

结合天台山特长隧道断层破碎带涌水处理的实例,分析了该隧道涌水现象的原因和涌水过程,阐述了隧道顺利通过断层破碎带集中涌水段的处治措施,主要方案为掌子面预注浆和径向注浆相结合。通过对治理过程的总结,得出了处理隧道断层破碎带涌水问题的一些共性特点,可供同类工程施工参考。

Combined with an example of water gushing treatment in the fault fracture zone of the Tiantaishan extra-long tunnel,analyze the cause and process of water gushing in tunnels,and explain the treatment measures for the tunnel passing through the fault fracture zone,for the main plan is the combination of pre-grouting and radial grouting.By summing up of the process proposed deal tunnel in Fault some common features of gushing water problem,a reference for similar projects.
