粘土隧道变形段处理方法研究

Study on Deformation Treatment of Clay Tunnel

针对密兴路改建工程火郎峪隧道变形事故,结合粘土围岩特性,对隧道变形段采取临时加固、注浆加固、增设刚拱桥、超前小导管加固等多种方法综合处理。结果表明,采用综合处理方法能有效防止隧道围岩变形的继续发生,保证隧道围岩的整体稳定性,确保隧道安全施工。

Aimed at the deformation accident of Huolangyu Tunnel of Mixing Road reconstruction engineering, combined with the engineering properties of surrounding clay rock, many methods such as temporary reinforcement, grouting, installing steel arch, advanced small tube and other measures have been taken to deal with the accident, and treatment effects were evaluated. The results show that using those measures can effectively prevented the continued occurrence of rock deformation, ensure the overall stability of surrounding rock and the safety of tunnel construction.
