Train-Induced Vibration Prediction and Control of a Metro Depot and Over-Track Buildings

To predict and control the train-induced vibration in depot buildings, a case study of Tianjin Metro, Line 5, was conducted. The platform has been constructed is use, construction over-track buildings not completed. Firstly, an situ measurement performed to obtain train loads validate numerical model. Secondly, finite element model track–soil–depot structure established. simplified as series two spring-mass models load simulated using measured rail acceleration. calculated results were validated by data. responses building be built, sub-system added Finally, effect isolation bearings discussed. indicate that vibrations exceeded guideline limits without mitigation measures some rooms building. dominant frequency floors 31.5 Hz. Vibration effectively mitigated vibrations, IL reached approximately 7–15 dB at about
