Combining with the current domestic and international research ideas response to tunnel through the active faults of the mainstream, this paper put forward a specific actionable comprehensive treatment for a highway tunnel. It combined a variety of designs including the over-excavation of tunnel trunk, lining section design, segmental flexible connection design and etc, so that the tunnel could pass the fault zone smoothly and meet safety and durability requirements during tunnel operation. Key words: tunnel; active faults; lining section; cutting deformation joint 1　概述 四川绵茂公路某拟建隧道隧址区分布有活动性 断层，断层错动影响带将对该隧道产生不利影响。本 活动性断层具有特殊的活动性和不稳定性，对 文基于该隧道工程探讨处理隧道跨活动断裂带的工 隧道结构的破坏可分为两种基
