Analysis of soil-foundation interaction by coupling finite and infinite elements

In many problems of physics or engineering, we are in the presence of infinite or semi-infinite domains. The analysis of these problems requires the use of size extended in order to model as well as possible the behaviour of the far field. In this paper, a technique of coupling finite elements and infinite elements was proposed to analyze the soil-foundation interaction problems under axisymmetric or plane strain conditions. In this numerical model, the soil-foundation interface was modelled by interface elements.
