摘　　要：综合采用地质物探、现场调查等手段,深入分析齐岳山隧道涌水原因,揭示了齐岳山隧道涌水机理,并制订相关防治技术,得到以下结论:(1)齐岳山隧道涌水的原因主要是涌水灾害源、涌水通道,且受到大气降水的影响较大:(2)齐岳山隧道涌水机理:隧道开挖扰动周围围岩体并使其发生应力重分布,从而导致隧道围岩经历弹性变形,连续损伤,塑性大变形及裂纹扩张等过程,最终形成涌水;(3)制订"以排为主,以堵为辅,排堵结合"的防治技术并成功解决了齐岳山隧道涌水问题,可为同类型工程提供理论依据和技术支撑。Comprehensive use the geological geophysical and field survey,deep analysis the reason of Qiyueshan gushed water,reveal the mechanism of gushed water in Qiyueshan Tunnel,develop prevention and control technology.The following results are obtained：（1） The reason of tunnel gushed water is mainly source of gushing disaster and water channel,and influenced by the atmospheric precipitation is larger;（2） Mechanism of Qiyueshan tunnel gushed water：Tunnel excavation disturbed surrounding rock mass and stress redistribution.The tunnel surrounding rock undergoes elastic deformation,continuous damage,plastic deformation and crack expansion process,and ultimately the formation of gushed water;（3） Develop a technique for gushed water control of ＂Mainly in drainage,supplemented by plugging,combine drainage and plugging＂ to solve the problem of Qiyueshan tunnel gushed water successfully,which can provide theoretical basis and technical support for the same type of engineering.
