| 摘 要： | 山岭隧道开挖经常遇到断层破碎带,开挖支护施工难度大,容易出现事故,是隧道施工的薄弱环节。文中结合史家山2号隧道,根据其地质特征,运用FLAC3D软件建立数值模型,对比了有无断层破碎带和不同工法下的穿越断层破碎带的工况,提出了断层破碎带的影响程度和适合的施工方案。

| Abstract: | Mountain tunnel excavation often encounters in fault fracture zone, resulting in that big dif- ficulty of the excavation and support construction and being vulnerable to accidents. It is the weak link of the construction of the tunnel. Combined with Shijiashan2 tunnel, according to its geological char- acteristics,the FLAC3D software is used to build model. Comparing to the conditions with or without the fault fracture zone and different working methods, this paper proposes the influence degree of fault fracture zone and the appropriate construction programs. |
