| 摘 要： | 借助于有限元方法,对裂隙各向异性介质一雏四分量弹性波场中横波双折射的有关问题进行了研究。它们是裂隙方位与相速度,双折射与震源主频,双折射与裂隙丰度,双折射与能量分配,双折射与延迟时,双折射及其振幅谱等。这些问题对深入认识横波双折射特性,对理论和实际工作都有一定帮助。

| Abstract: | In this paper, using finite element method, the authors researched and discussed shear wave splitting with 1 - D 4 - C wave field in anisotrieal medium containing cracks. The searching includes crack's azimuth and phase's velocity, splitting and frequency of source; splitting and crack's density, splitting and energy distributing, splitting and delay time, splitting and amplitude spectrum and so on which would be heepful to understand fracture of shear wave splitting thorouthly, and do a good favour to the theory and practice work. |
