The problem on the dynamic response of a rigid embedded foundation in the presence of an underground rigidtunnel and subjected to excitation of incident anti-plane SH waves is analyzed. By using the exact analytical solution for thetwo-dimensional SH-wave propagation in and around both the surface rigid foundation and subsurface rigid tunnel, thoseaspects of the resulting ground motions that are of special interest and importance for seismic resistant design in earthquakeanalyses have been examined. The computed amplitudes of the resulting periodic ground motions display a very complicatedwave-interference between the surface foundation and underground tunnel that lead to observed standing wave patterns,together with abrupt changes in the wave amplitudes and large amplification of the incident motions.
