摘要
横波在穿越裂隙介质时会分裂成平行裂隙的快横波和垂直裂隙的慢横波,其偏振角随着波传播的时间和空间而变化。利用角度谱可以有效地求取偏振角,从而分离快慢横波。这里介绍了角度谱的概念及其应用。
Shearwave will split into fast shearwave parallel to fracture strike and slow shearwave vertical to fracture strike when shear-wave passes through fractured medium, its polarization angle varies with traveling time and space of shear-wave. The polarization angle can be effectively calculated from angular spectra, therefore fast and slow shearwave can be separated. In the paper, we introduced the concept and its application of angular spectra.
