The vibration issue of high-speed railways has become a significant concern in China, prompting the development and evaluation of novel vibration-damping track (VDT) structures. This study investigates the vibration modes and mechanical behavior of a newly designed VDT structure for CRTS III slab tracks using finite element analysis. Key findings include: (1) Vibration Modes: The VDT track demonstrates significantly lower natural frequencies (29–32 Hz) compared to the CRTS III track (107–114 Hz), enhancing energy dissipation and noise reduction. (2) Mechanical Behavior: Under vertical loads, the VDT track experiences higher tensile stresses in the SCC layer and slab, requiring enhanced reinforcement, particularly in longitudinal and transverse directions. (3) Temperature Gradient Effects: Vertical displacement of the VDT slab is reduced, while tensile stresses and displacements are comparable to CRTS III under negative gradients. (4) Track Irregularities and Gauge Changes: Temperature gradients induce slight vertical irregularities and minor gauge expansions or reductions, with no significant operational impacts. (5) Transition Section Requirement: A specially designed transition section is essential to mitigate displacement differences between CRTS III and VDT tracks under temperature gradients. This research highlights the VDT track's potential for improving vibration reduction and operational safety in high-speed railway systems.
