| 摘 要： | 针对横观各向同性饱和两相介质的弹性波动方程组,应用基于显式逐步积分计算格式的时域显式有限元方法对其在输入地震波作用下的动力反应进行计算和分析,并将计算结果与完全各向同性饱和两相介质的计算结果进行对比研究。结果显示横观各向同性饱和两相介质与完全各向同性饱和两相介质的动力反应具有较为显著的差异。同时表明时域显式有限元方法是进行横观各向同性饱和两相介质动力反应计算分析的一种有效方法。

| Abstract: | The time-domain explicit finite element method that based of explicit step-by-step integral format is used to solve the elastic wave equations of transversely isotropic fluid-saturated media,and the elastic dynamic responses of the media under input earthquake wave are calculated and analyzed.The result is compared with one of completely isotropic saturated media also.The result shows that the dynamic response has significant difference between two kinds of media.The numerical calculation indicates that the... |
