No suitable handy tool is available to predict train induced vibration on environmental impact assessment. A simple prediction model is proposed which has been calibrated for high speed trains. The model input data are train characteristics, train speed and track properties; model output data are soil time averaged velocity and velocity level. The proposed model has been calibrated by means of a measurement campaign led along an Italian high speed rail line. Vibration have been measured during ETR500 passage. Model results are obtained in terms of maximum soil r.m.s. velocity and vibration level. The model can be validated by comparing high speed train measured vibration levels with the predicted ones.

Abstract
No suitable handy tool is available to predict train induced vibration on environmental impact assessment. A simple prediction model is proposed which has been calibrated for high speed trains. The model input data are train characteristics, train speed and track properties; model output data are soil time averaged velocity and velocity level. The proposed model has been calibrated by means of a measurement campaign led along an Italian high speed rail line. Vibration have been measured during ETR500 passage. Model results are obtained in terms of maximum soil r.m.s. velocity and vibration level. The model can be validated by comparing high speed train measured vibration levels with the predicted ones.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
