| 摘 要： | 时域边界元方法是研究层状与各向异性介质波动问题的有效工具，本文对其研究背景和进展情况进行了扼要评述。在此基础上，将其运用于对某电站地下厂房在地震波作用下的波动响应分析，通过求解地下厂房的位移响应和应力响应并比较地基介质的各向异性程度，入射波的角度及频率对波动响应的影响，获得了对工程具有重要参考价值的规律。

| Abstract: | The dynamic response of an underground powerhouse under seismic waves is studied by time domain BEM for anisotropic media. The responses of displacements and stresses are evaluated. The effects of angle and frequency of incident waves and the degree of media anisotropy on dynamic response of the underground structure are analyzed in detail. Some important findings for engineering are obtained. |
