摘　　要：采用有限元与无限元耦合方法讨论交通隧道在地震波作用下震动反应问题 ,并考虑地基土的非线性与层状性 .运用等效线性模型处理土的非线性 ,Newmark-β求解动态平衡方程 .通过实例计算 。A coupling of finite elements(FE) and infinite elements(IE) method is presented to investigate seismic response of the transportation tunnel due to earthquake waves. The foundation, consisting of non linear and layered soil modeled with equivalent linear approach, and elastic rock in the half space, is discretized into FE and IE. Newmark β time integration is employed to solve the equation of motion. Besides, the earthquake response of lining has been examined through engineering calculation.
