In evaluation of train-induced vibration from subway tunnels, it is important to grasp the property of vibration propagation though the ground. Vibration acceleration is measured both at tunnel lining and on the ground surface on the subject of a subway shield tunnel. At the same time, propagated vibration is calculated by 2-D Finite Element Method by inputting the measured vibration acceleration near the track in the tunnel. The comparison between calculated and measured results verifies the numerical calculation method applied in this paper. Accordingly, the property of propagated vibration is investigated based on the measured and calculated method.
