Field measurements were conducted on the ground and the basement floor of a building with undergroundcontinuous wall to investigate the subway-induced vibration.Then,the changes of acceleration peak attenuationrate,Fourier spectrum,Hilbert marginal spectrum and vibration level were analyzed according to the data obtainedat the related measuring points.Finally,the vibration isolation effect of the continuous underground wall and the vibrationattenuation on each floor of the basement wall with vibration isolation were discussed.The results show thatthe vibration isolation effect of continuous wall is obvious in horizontal direction but is rare in vertical direction,thatthe degree of horizontal vibration attenuation increases with the depth of underground construction,that the verticalvibration attenuation is obvious on each layer of the basement,that the vibration levels in the three directions all increasewith the center frequency,and that the attenuation degree of horizontal vibration level increases with thedepth of underground construction.
