Abstract
In this paper, the foundation soil of a structure is simulated as a two-phase saturated porous medium. The dynamic equations of a porous medium and finite element formulations based on the variational principles are given. For the structural analysis, the technique of multilevel substructure is used, and the analysis of saturated soil is set on the highest level substructure model. For the treatment of wave reflection on the artificial finite element boundaries in the semi-infinite foundation, a generalized Smith non-reflection boundary method is developed. Based on these theories, a dynamic finite element analysis program DIASS for interaction analysis between two-phase saturated soil foundation and structure has been developed. The numerical examples are given here to illustrate the influence of water in pores in the soil on structural responses.
