摘要
以兰渝铁路马家山隧道施工为例,介绍了大断面软弱围岩隧道变形控制的方法,具体阐述了通过将注浆纳入工序化管理,加强对围岩的径向预注浆、二次注浆等,进而控制围岩变形的施工技术措施,对同类隧道工程具有一定指导意义。
Taking Majiashan tunnel construction of Lanzhou-Chongqing railway as an example, this thesis introduces tunnel deformation control- ling methods of large cross-section soft-weak surrounding rock, specifically expounds construction technical measures for controlling adjacent rock deformation by putting grouting into fine processes management and strengthening radial pre-grouting and second grouting for adjacent rock, which has certain guiding significance for similar tunnel engineering.
