为了探讨隧道的纵向地震响应特性，本文采用TDAPⅢ软件，结合反应位移法对日本一地下交通隧道A号线的开挖段进行纵向地震响应分析。通过建立合理的隧道模型，考虑土与隧道结构之间的相互作用，探讨了隧道中连接设计对地震响应的影响，得到了隧道结构的内力和变形。分析结果表明：在地震作用下，隧道结构剪力、连接弹簧剪切变形量及其张开量均未超过相应限值，而结构的弯矩在389 m处测点附近非常接近限值，应当将此处作为抗弯薄弱位置并加强该处的抗弯性能。

In order to investigate the longitudinal earthquake response characteristics of the tunnel,this paper made the longitudinal earthquake response analysis of one Japanese underground traff ic tunnel excavation section in line A by using the TDAPⅢsoftware and combining with the response displacement method.Through constructing reason-able tunnel model,the inf luence of the tunnel connection design on the earthquake response was discussed and the internal force and deformation of tunnel structure was concluded by considering the interaction between soil and tunnel structure.The analysis results showed that the tunnel structure shear,connecting spring shear deformation and its opening amount don't exceed the corresponding limit under earthquake action, the structure bending moment is very close to the limit near the measuring point of 389 m,which means this point will be viewed as an bending weak position and the bending resistance performance of this point should be strengthened.
