In order to improve the quality of the superstructure property and reduce the impact of vibration and noise,it is necessary to carry out targeted vibration and noise reduction analysis.Based on the finite element model and combined with the analysis of the vibration and noise reduction measures of the superstructure property of the typical depot in China,the prediction of the track vibration and noise reduction scheme is proposed for the second floor of the parking lot,and according to the comparison of the results of the finite element prediction after using the vibration and noise reduction scheme and the no measure scheme,the vibration and noise reduction effects of the second floor climbing line,throat area and library line are increased by 15.9％,30.1％and 9.9％respectively The research results can provide construction experience for the vibration and noise reduction of the above-ground subway double-storey parking lot project in the future.
