摘　　要：海底隧道在穿越断层及软弱破碎带时如果遇到透水性地层,可能会发生隧道突水涌泥,如何妥善处理这些潜在危害对于顺利建成海底隧道至关重要。结合建设中的厦门海底隧道工程,针对隧道通过不良地质时可能遇到的突水涌泥危害,对突水的补给水源、突水通道及隧道与含水层位置关系进行了分析,同时引用В.斯列萨列夫简支梁及强度理论,对海底隧道突水条件及预测方法进行了理论分析。在参考国内外经验的基础上,给出了海底隧道突水涌泥的治理对策,为海底隧道的顺利修建提供了指导。When the subsea tunnel crosses the fault zone and weak rock mass stratum, if there is a hydraulic permeability stratum in front of the tunnel face, the water inrush and burst mud would be likely to happen in tunnel. How to treat these potential hazards is very important for successful construction of the subsea tunnel. Depending on Xiamen subsea tunnel being built, a system analysis on the runoff source and water inrush pathway and the relationship between tunnel and hydraulic permeability stratum is implemented. A theory analysis on the condition and prediction method of water inrush and burst mud in the subsea tunnel by quoting B.Silishalif free beam and intensity theory is followed. Basing on the domestic and oversea experiences, some countermeasures of water inrush and burst mud in the subsea tunnel are given, which will provide a guidance on the subsea tunnel construction.
