Abstract: | Considering engineering practice, the viscoelastic two-phase model is adopted, seismic wave propagation in saturated rock
is studied. Not only the effect of the viscosity of rock skeleton but also the effect of ground water on the propagation of
the seismic wave can be considered by this model, the propagation characteristics of seismic wave in saturated rock can be
understood comprehensively and the model is more reasonable than other model by which seismic wave propagation is studied.
The effect of frequency, water content and viscosity constant on the wave velocity and attenuation are studied by numerical
examples and some valuable conclusions are drawn. |
