摘要：The high-speed railway CRTSIII ballastless track, subjected to complex strip structural systems, high-cycle fatigue loads, and intricate rainwater environments, faces significant maintenance challenges due to interlayer disconnection and crack propagation. This study investigates the cavitation and dehollowing damage mechanisms in rainy areas, focusing on the water dynamics within track interlayer cracks. Numerical simulations using ANSYS-FLUENT software were conducted to analyze the cavitation phenomenon and its impact on the structural integrity of the track. The findings provide insights into the damage progression in rainy regions and contribute to a better understanding of the underlying mechanisms.
