Vertical and Rocking Impedances for Surface Rigid Foundation Resting on a Transversely Isotropic Half-Space

The vertical and rocking impedances of a rigid foundation resting on a semi-infinite transversely isotropic medium are obtained in the frequency domain. In the present approach, the contact pressure distribution on the soil foundation-interface is approximated by a linear combination of known pressure patterns. It is shown herein that the approximate solutions of spatial displacement distributions satisfy quite well the boundary conditions for this mixed boundary problem.
