本文用各向异性反射率法计算爆破源反射地震的理论地震图。对比了各向同性介质的反射记录，讨论了水平叠层各向异性和裂隙各向异性对体波三分量记录特征的影响。结果表明，裂隙各向异性导致转换横波分裂，并使横向记录分量出现波动。这种转换横波的分裂和快渡偏振方向的定向性难以用各向同性和水平横向各向同性传播来模拟。由此提出，爆破源反射地震三分量记录中横向记录剖面上出现的可连续追踪的转换波是探测介质方位各向异性的一个重要标志。
In this paper, the theoretical seismogram of blasting source reflection earthquake is calculated by anisotropic reflectivity method. The reflection records of isotropic media are compared. The effects of horizontal anisotropy and crack anisotropy on the three-component recording characteristics of bulk wave are discussed. The results show that the fracture anisotropy leads to the transformation of shear-wave splitting and the fluctuation of transverse recording components. The splitting of this transversal shear wave and the polarization direction orientation of the fast crossing are hard to model with isotropic and horizontal transversally isotropic propagation. It is thus pointed out that the continuously tracable converted wave appearing on the lateral recording profile in the three-component recording of the reflection source of the blasting source is an important indicator of the azimuthal anisotropy of the detection medium.
