Description
On ballasted track, to prevent track irregularities from growing is important in order to keep good riding comfort. The roadbed vibration caused by train have a great influence on the growth of track irregularities. In this study, we considered the influence of roadbed vibration on track settlement by experiments using full-scale ballasted track model and simulation using the Discrete Element Method. As a result of the study, it is quantitatively showed that the track settlement increases as the roadbed vibration increases. Further, it is clarified that the track settlement rapidly increases if the roadbed acceleration exceeds the gravitational acceleration, and that the track settlement correlates with the velocity amplitude of the roadbed.
