Abstract：Based on a subway station and its superstructure in the coastal soft soil area of Fuzhou，the propagation of train vibration waves in the five-story superstructure in the throat area was analyzed through field testsand numerical simulations.The study shows that：the vibration of the floor slab of the superstructure room shows the trend of atenuation and then amplification along the floor，and the vibration excellence frequency band of each floor is 40Hz～80Hz ，in which the peak frequency of the first floor is 63Hz ，and that of the third and fifth floors is both 50Hz ； the vibration of the room columns of each floor is greater than that of the stairwell columns，and the vibration of the room columns shows the trend of atenuation and then amplification along the floor，and the vibration of the stairwellcolumns is basically unchanged in all the floors； VLzmax of vertical crossver frequencyof thefloorslabof the first floor and the fifth floor exceeds the limit by15.2 dB and 3.2dB ，respectively，and the VLzmax of the room column and the stairwell column of each floor does not exceed the limit; VLzmax of the upper floors can be reduced by 2.2dB～5.1 dB when the column cross-sectional size is increased to 0.5m×0.5m ，and VLzmax can be reduced by 1.4dB～2 dB when the floor thickness is increased to 0.2m . Results of this research can provide theoretical reference for the research and optimal design of train vibration response of subway stations and their superstructures.
