In this paper, it is investigated how free field vibrations d ue to vibratory pile driving are affected by the soil stratification. Free field vibration s are calculated by means of a coupled FE-BE model, based on a subdomain formulation. Results are examined in the frequency range from 5 Hz to 100 Hz. RESUME- Dans cet article, on etudie comment les vibrations en champ libre dues au vibro- foncage sont affectees par la stratification du sol. Les vibrations en champ libre sont calculees a l'aide d'un modele couple FE-BE base sur une formulation de sous-structuration. Les resultats sont examines dans la gamme de frequences entre 5 Hz et 100 Hz.
