Abstract
This paper has dealt with the computer simulation of the high-speed train induced ground vibration. The track loading is assumed by a set of harmonic moving function of different frequencies in view of a train geometry (axle distances of a car and connection of cars). Besides, sleeper distances and other vibration factors involved are of essence for the periodicity of alongside vibration so that an inverse analysis is introduced to the measured data for the Shinkansen train running. The 2.5 dimensional FEM-BEM method developed by the authors is used for the analysis. Thus simulated ground vibration results in a good prediction for the attenuation of alongside vibration acceleration value (VAL) in case of flat track and an acceptable prediction for embankment track.
