A Unified Approach for the Prediction of Vibration Induced by Underground Metro

In this paper a methodological approach employing a mathematical model to evaluate the vibration level transmitted by railway traffic is proposed. The originality of the approach is related to the explicit coupling of a vibration generation model which is based on the dynamic interaction between the railway vehicle and the superstructure with a vibration propagation model that analyses the dynamic interaction between the railway superstructure and the underlying soil/structures. The vibration level provided by the prediction model has been compared with vibration measurements carried out on a test site located along Turin underground line.
