The novelty of straddle-type railway stations as a modern railway infrastructure necessitates thoroughly examining their vibration behavior under high-speed train-induced vibrations. This study focuses on Shangrao station, the inaugural straddle-type high-speed railway station in China, to investigate its vibration properties induced by high-speed trains. A comprehensive finite element model is developed and validated against empirical data to ensure accuracy. The vibration response and propagation patterns induced by railway operations are extensively studied under diverse operational conditions. The results illustrate that the peak acceleration in the vertical (Z) direction significantly exceeds that in the horizontal (X and Y) directions in most test cases. Moreover, under consistent train speed and axle load, the multiple parallel traffic scenario results in higher peak accelerations in all directions compared to the grade separation traffic scenario. Additionally, a positive correlation exists between the railway platform's maximum amplitude, corresponding frequency, and train speed. Furthermore, increased train axle load leads to higher peak accelerations in the station building. The findings of this research offer valuable insights for the predictive modeling and design of high-speed straddle-type railway stations, providing essential technical support for future station projects.
