In the preceding paper, we made clear the absoptive process and its mechanism of the crushed stone ballast when the impact load acted on the head of the rail which was connected to the wooden and the concrete sleeper blocks separately. In this study, the authors are so interested in the behavior of track ballast excited by the impact loaded motion and so eager to know what phenomena will occur at any point in the ballast during the impact disturbance, that the analyzing method by the wave propagation theory will be mainly used in proceeding the study. We try to clarify the characteristics of the stress wave propagation through track ballast when it is excited by such an impact disturbance. In performing the theoretical analysis some adequate assumptions are uaed in order to make the mathematical treatment possible.
