the dynamic responses of elastic half-space-sediment-ideal fluid system due to SV wave incidence are investigated. The sediment is modelled respectively as the elastic solid
viscoelastic solid
ideal fluid and vsicous fluid. The results obtained are compared with the case in which sediment is viewed as a two-phase poroelastic medium. It is found that the two-phase poroelastic medium can be simplified approximately as a viscoelastic solid when its permeability is relatively small (k≤10-3 m/s).
