•We study wave propagation in a stratified poroelastic seabed submitted to spherical acoustic waves.•An axisymmetric analytical formulation based on Hankel-Fourier transforms is presented.•A degenerated half-space test-case is used to validate the model.•We extend the results to a realistic multilayered seabed, composed of ten layers presenting different properties.
This paper deals with the study of axisymmetric wave propagation in various acoustic/porous stratified media coupling configurations. It presents the theoretical developments of a semi-analytical method, its validation for a limit test-case half-space ground, and an extension to a realistic multilayered seabed, when spherical waves are emitted from a transient point source in water.
