| 摘 要： | 论述了地壳介质中存在的各类向异性及其弹性本构关系，推导了应变能变换公式、ＥＤＡ薄层各向异性弹性常数及非对称面上ＥＤＡ构成的单斜对称弹性常数的计算公式；讨论了几种各向异性对称系统的本征方程并给出了弹性波的角散表达式，最后选取合理的参数对波的角散现象作了数值模拟。

| Abstract: | In this paper,various elastic constructive relations of anisotropic earth media are discussed as well as the angular dispersion of elastic waves. Besides application of previous authors equations, for these works several important equations are introduced and derived by the present authors, such as a transform equation of strain energy, the elastic modulus of thin layered EDA media and modulus of EDA media in non-symmetry observation profile. Finally, some numerical examples of angular dispersion of elastic waves are simulated by selecting suitable parameters. |
