Influence of anisotropic properties on vertical vibrations of circular foundation on saturated elastic layer

In this paper, the influence of anisotropy material properties on vertical vibrations of rigid circular foundation resting on a transversely isotropic poroelastic layer with finite thickness and a rigid base is studied. The contact surface between foundation and saturated layer is smooth, and either permeable or impermeable. This dynamic interaction problem is investigated by employing a discretization technique and the Hankel integral transform method. The proposed numerical solution scheme is validated with existing solutions, and selected numerical results are presented to portray the influence of anisotropic properties and other parameters on the vertical compliance of the foundation.
