【摘要】 随着跨断层隧道工程近年来不断增多，如何确保断层错动作用下衬砌结构和工程设施的安全、减小因断层错动造成的灾害损失是进行隧道建设无法回避的问题。为此，首先介绍了断层的类型、力学性质和作用机理，然后分析阐述了国内外关于隧道穿越断层常用的抗错断处理措施及建议。最后通过比较得出结论，超挖设计是目前最为常用的防护手段，而铰接设计和隔离消能设计对隧道的抗错断效果最为显著。更多还原

【Abstract】 In the background of the increasing number of cross fault tunnel projects in recent years, how to ensure the safety of lining structures and engineering facilities under fault displacement, and reduce disaster losses caused by fault displacement, is a critical problem in tunnel construction. The types, mechanical properties, and mechanisms of fault displacement are first introduced, and then the commonly used anti fault treatment measures for tunnel crossing faults are analyzed and elaborated. It is conclude that overbreak design is currently the most commonly used protective measure, while hinge design and isolation energy dissipation design have the most significant anti fracture effect on tunnels.更多还原
