ABSTRACT

In the present investigation, the scattering characteristics of Love waves due to the surface irregularity in a transversely isotropic layered poro-viscoelastic rock structure have been studied. The effects of the anisotropy parameter and porosity parameter of the upper layer on the phase and attenuation coefficient of Love waves have been analyzed. The expressions for the induced reflected displacement have also been obtained for different types of surface irregularity, viz. parabolic type, rectangular type, and triangular notch type in the considered layered rock structure. The behavior of reflected displacement under the efficacy of several physical parameters has also been examined.

摘要

在目前的调查中，已经研究了由于横向各向同性层状多孔粘弹性岩石结构中的表面不规则性导致的 Love 波散射特性。分析了上层各向异性参数和孔隙度参数对洛夫波相位和衰减系数的影响。对于不同类型的表面不规则性，也已经获得了诱导反射位移的表达式，即。所考虑的层状岩石结构中的抛物线型、矩形型和三角形缺口型。还检查了在几个物理参数的作用下反射位移的行为。
