Characterization of Road Vehicle Induced Soil Vibration

An original method to evaluate vibration levels due to road vehicles is proposed. A measurement campaign has been carried out to individuate vibration acceleration levels for different typologies of vehicles. Each vehicle passage has been considered as a single event. Vibration levels due to each single event have been measured by means of a data acquisition system. Measurement results allowed to individuate the relations among vibration levels, typology of vehicle, vehicle velocity and soil characteristics. Thus, acceleration levels may be estimated at different distances from the vibration source by adopting a propagation model which has been previously proposed for train induced soil vibrations.
