中文摘要：

依据地震波衰减效应确定模型的动力加载方式,将计算得到的地震波输入到能够考虑隧道与断层不同相对位置的典型数值模型中,研究断层破碎带影响下隧道结构的地震动力响应规律。研究结果表明：隧道与断层破碎带的相对位置关系对震害程度影响显著;隧道位于断层上盘时,地震动力响应比相交或位于下盘的情况剧烈;地震破坏主要发生在边墙肩部和角部位置,且断层破碎带与地震作用方向的夹角较小时,隧道结构的动力损伤较严重。

英文摘要：

Seismic wave attenuation rule was studied to determine the loading method of computing models. The cal- culated seismic wave was input to typical numerical models considering different relative location of fault and tunnel, and the calculation results were analyzed to discuss the seismic dynamic response rule of tunnel. The study results prove lhat relative location of a tunnel and fault has significant effects on the seismic damage. For a tunnel situated in upper wall, the seismic dynamic response is more severe than those of the tunnels which intersects the fault or is sit uated in footwall. The lining damage occurs mainly in the shoulder and corner of the sidewall,and the damage is more serious when the angle between fault fracture zone and seismic oscillation direction is small.
