DEVELOPMENT OF EMPIRICAL EQUATIONS TO ESTIMATE THE TRAIN-INDUCED GROUND VIBRATION

초록

Recently, the influence due to the ground vibration from the passing train has been an issue and should be considered. In this study, the train-induced ground vibration was measured at various locations in the conventional lines and the database was constructed through the measurement. The characteristics of train-induced ground vibration were categorized and the empirical equations for estimation of ground vibration were developed. The empirical equations were developed in terms of vertical vibration level (dB(V)) related to the distance from the source. The database and empirical equations can be used for the prediction of train-induced ground vibration and countermeasures against vibration pollution in conventional lines."
