| Popis: |
Measurements have been made for ground vibration at four different sites where the existing track form was replaced by one with a much lower vertical stiffness. Other parameters, such as the rail roughness level, were controlled such that these measurements allow a direct comparison to be made between the ground vibration levels obtained for the two different track forms. It is found that the more resilient track form does bring about a significant reduction in ground vibration in the part of the frequency range expected from computer models. The performance of the more resilient track form differs from expectations based on the results of the models in the lower part of the frequency range of interest at some sites. The potential causes of this difference are discussed with reference to the measurements. |
