摘要

针对穿越活动断层区隧道的结构设计,提出活动断层区隧道结构的抗断设计对策;对"超挖设计"和"铰接设计"两种抗断设计方法进行了讨论;提出了"铰接设计"中隧道节段长度及节段间连接抗剪刚度的计算方法,并分析了连接剪切失效后隧道节段的运动特征。
Aiming at the problem of structure design of a highway tunnel crossing active faults zone,protective design strategies of breaking resistance are put forward;and then over-excavation and articulated design are discussed.The calculation methods of the length of the single segment geometry and the shear stiffness of the joints are proposed.In addition,tunnel element kinematics after joint rupture is analyzed.
