摘要
研究地震波在各向异性介质中的传播规律是勘探地震学领域中的一个重要内容。本文首先讨论了2.5维波动方程。其次,在2.5维空间,用有限元数值模拟方法模拟了裂隙各向异性介质波场,结果用波场切片做了显示。最后对模拟结果做了基本分析讨论,这里讨论的模拟方法也适用于其它类型的各向异性介质。
Studying seismic wave propagation in anisotropic media is an important content in survey geophysics. At first, 2.5D elastic equation is discussed. Then, the finite element method is used for synthetic in 2.5D space anisotropic media containing cracks. The results are showed by time snapshot. Finally. synthetic results are analyzed and discussed. This studied method of synthetic field can be also used to other anisotropic media.
