| 本文采用Ｌａｐｌａｃｅ－Ｆｏｕｒｉｅｒ联合变换及传递矩阵方法导出了正交各向异性层状弹性半平面动力问题的时域奇异解的解析表达式，讨论了奇异解的数值实施。并把奇异解应用于边界元，计算了地下直墙拱结构的动力响应问题。 |
| 英文摘要: |
| In this paper,the dynamic singular solutions of problem for the orthotropic layered elas-tic half-plane are derived in time domain with the aid of Laplace-Fourier mixed transforms and transfer matrix method.The numerical computation of these solutions is also discussed.By applying these solutions to the boundary element method , the numerical computations for the dynamic response of underground arch wall structure are proposed. |
