| 描述 | This book presents the theory of waves propagation in a fluid-saturatedporous medium (a Biot medium) and its application in Applied Geophysics.In particular, a derivation of absorbing boundary conditions inviscoelastic and poroelastic media is presented, which later is employedin the applications.. .The partial differential equationsdescribing the propagation of waves in Biot media are solved using theFinite Element Method (FEM).. .Waves propagating in a Biot mediumsuffer attenuation and dispersion effects. In particular the fastcompressional and shear waves are converted to slow diffusion-type wavesat mesoscopic-scale heterogeneities (on the order of centimeters),effect usually occurring in the seismic range of frequencies. . .Insome cases, a Biot medium presents a dense set of fractures oriented inpreference directions. When the average distance between fractures ismuch smaller than the wavelengths of the travelling fast compressionaland shear waves, the medium behaves as an effective viscoelastic andanisotropic medium at the macroscale.. .The book presents aprocedure determine the coefficients of the effective medium employing acollection of time-harmonic compressibility and she |
