Abstract

The ground vibration generated by the Shinkansen, Japanese super express train,can be problematic for people and structures nearby. The purpose of this study is to make clear the mechanism of the ground vibration generated by a train and to develop a numerical simulation tool which can quantitatively evaluate the effect of wave filtering. This study is consist with 2 parts: First, the Doppler effect in the field vibration data from train motion is shown to be found via FK spectrum. Second, the generation of ground vibration is classified by this numerical simulation. The ground vibration is caused by inhomogeneous media, inhomogeneous force from the train or discrete structure, like an elevated bridge. This work does not investigate the boundary problem between the train body and the ground, thus is a qualitative basic study.
