Abstract (EN): This paper describes the implementation and validation of a numerical methodology which can be used in the prediction of vehicle induced vibrations. The presented methodology is formulated in the time domain for the three-dimensional case. Although presented in the context of vehicle induced vibrations it can be adopted in the study of general problems of dynamic soil-structure interaction in which the structure lies on the surface of the soil. The method is based on the coupling of the fundamental Green functions to a finite element code (FEMIX). Some relevant aspects of the implementation are briefly discussed and a numerical example based on the study of the dynamic response of a slab resting on a homogeneous halfspace and subjected to the passage of a moving load is presented.
