We conducted on a study on a method of calculating ground vibration around a girder-type viaduct. This work focuses on the motion of the pier caused by the passing trains. Vibration acceleration in the pier at time of train passage was measured. Measurements revealed that vibration consisted chiefly of vertical translational behavior and rotational behavior around the horizontal axis. Analysis of ground vibration by axisymmetric finite element method considering these motions as excitation force characteristics was carried out. It was confirmed that the calculation results reproduce the ground vibration in the frequency range below 40 Hz.
