Abstract

The purpose of this study is to make clear the mechanism of the ground vibration induced by trains and to develop a numerical simulation tool which can quantitatively evaluate the effect of wave filtering works. A 3D viscoelastic finite-difference method is used to study the mechanism of the ground vibration induced by train. At first, the two special cases are tested. The force from train is constant for place and not-constant. The ground vibration does not happen in the former case. So the not-constant force from the train is measured. Finally, a numerical simulation is promoted by using this inhomogeneous force from the train. The result of this numerical simulation qualitatively and quantitatively resembles field ground vibration data. It is recognized that one reason of the generation of the ground vibration is caused by inhomogeneous force from the train.
