Dynamic interaction between multiple rigid strips and transversely isotropic poroelastic layer

The influence of anisotropic and poroelastic effects on dynamic compliances of multiple rigid strip foundations bonded to a transversely isotropic poroelastic layer is studied in this paper. The dynamic interaction problem is investigated by employing a discretization method based on the rigid body displacement boundary conditions at each strip-layer interface. The present discretization technique yields a flexibility equation system to determine the contact traction with the aid of the influence functions. Comparisons with several existing solutions are presented and selected numerical results for non-dimensional compliances of a system of two rigid strips are shown to portray the influence of various effects on the foundation response.
