摘 要: 基于孔隙介质的Biot理论,推出了横向各向同性液体饱和孔隙岩石中平面波传播的特征方程,获得了四种波:第一准纵波(QP1)、第二准纵波(QP2)、准横波(QSV)和反平面横波(SH)的传播速度及衰减系数的解析表达式,并给出了频散曲线和衰减曲线的数值结果。最后还讨论了各类准体波位移之间的耦合关系。 Based on the Biot's theory for fluid-saturated porous media,the characteristic equations of the plane waves propagating in transversely isotropic porous rock are derived.The analytic solution for velocities and attenuations of four waves:the first and second quasi-longitudinal waves(QP1 and QP2),the quasi-transverse wave(QSV) and the antiplane transverse wave(SH) is obtained.The curves of dispersion and attenuation are illustrated.Finally,the coupling relations between three quasi-body waves are discussed.
