3-D foundation-soil-foundation interaction D.L. Karabalis & C.-F.D. Huang Department of Civil Engineering, University of Caro/mo, ABSTRACT A direct time domain BEM formulation is used for the solution of a class of dynamic foundation-soil-foundation interaction problems. A set of parametric studies, in the form of time and frequency dependent plots, is presented illustrating the influence of a number of parameters upon the response of the soil-foundations system. INTRODUCTION Dynamic soil-structure interaction (SSI) analysis pertaining to the single foundation problem has been well established on the basis of numerous rigorous investigations during the last three decades. In contrast, relatively few works regarding the phenomenon of dynamic foundation-soil-foundation interaction (FSFI) have been reported since the early works of Whitman [1] and Warburton zf a/. [2,3] have identified the importance of such a dynamic interaction. Among the later works on the subject on
