Simplified model of subsoil-structure interaction

Abstract eng:
During the past three decades a great deal of research work has been carried out on numerical modelling of soil-structure interaction. This paper starts from a review of governing equations describing creep in the upper-structure, consolidation taking place in the subsoil, and characterizing interactions between the two sub-domains (Sec. 2). This general model is then simplified by admitting a two-parameter model of a foundation layer in which the liquid prevailingly flows in the vertical direction (cf. Sec.2.2). Simple examples illustrate the applicability and effectiveness of the model (Sec. 3).
