Image-traced flow behavior and frequency-dependent response of ballasted trackbed under dynamic loads

Key Points

• The study shows that frequency-dependent response significantly affects the flow behavior of ballasted trackbeds under dynamic loads.
• Key evidence indicates that varying dynamic loads can alter the stability of the trackbed structure, influencing performance metrics.
• Analysis of trackbed response utilized image tracking techniques to visualize flow behavior when subjected to dynamic loads.
• This research may enable better design practices in rail infrastructure to enhance safety and performance in varying load conditions.
