Summary

We developed 3-D dynamic interaction analysis method that was able to model the entire railway system including the vehicle, the track, the structure and the ground. We conducted ground vibration analyses in which ground properties and track structure were assumed to be analytical parameters. As a result, under the condition of this analysis, it became apparent that ground vibration decreased by 25 dB when Vs (shear wave velocity of the ground) was increased to 1.3 Vs. On the other hand, it increased by 15 dB when Vs was decreased to 0.7 Vs. Moreover, we made clear the vibration-reduction effect of vibration-reduction track.
