摘要
采用有限元－人工透射边界方法计算了含有地下隧道工程的地基在ＳＨ波和瑞利波作用下的地震动反应，讨论了各自不同的地震动特性。并通过与边界积分方法比较，验证了有限元—人工透射边界方法对解决此类问题的有效性。
In this pape the earthquake motions in the foundation containing a tunnel structure excited by SH incident wave or Rayleigh incident wave are computed with a finite element-artificial transmitting boundary method.The characteristics of the earthquake motions in both cases are discussed separately. The efficiency of above-mentioned method for solving these problems is tested by comparison with the boundary integral method.
