【 摘 要 】

This paper presents dynamic response of two rigid foundations resting on a multi-layered poroelastic medium under time-harmonic vertical loading. The contact surface between the foundations and the layered medium is assumed to be smooth and fully permeable. This dynamic interaction problem is studied by employing a discretization technique and an exact stiffness matrix scheme. The accuracy of the present solution is verified and selected numerical results for impedances of two square foundations are also presented.
