采用数值分析方法,研究了隧道断层破碎带对施工期间拱顶位移、边墙主应力以及喷射混凝土内力的影响。分析结果认为,隧道开挖时,对断层带的拱顶下沉位移影响较大,但存在一定的影响范围。隧道拱顶和边墙发生塌方破坏的可能性最大,需要加强对断层带隧道施工过程的围岩变形监测,确保施工安全。 The numerical analysis method is used to study the influence of tunnel fault fracture zone on dome displacement, main wall stress and internal force of shotcrete during construction. The results show that tunnel excavation has a great influence on the vault settlement of the fault zone, but it has some influence range. The vault and sidewall of the tunnel are most likely to collapse and collapse, and the deformation monitoring of the surrounding rock during tunnel construction of the fault zone needs to be strengthened to ensure the construction safety.
