This paper studies the characteristics of ground vibrations, due to metro trams and their propagation laws. The study consists of the simulations of the train-track system vibration, which provides the excitation loads of moving trains onto the tunnel structure, and the calculation of the track-tunnel-ground system vibration, by which the propagation properties of ground accelerations and velocities are studied. The main results show that there exists a vibration amplifying area in certain distance away from the tunnel center, where the ground accelerarations may become higher by certain level, and the ground peak velocities PPV may get greater than the allowable limit. The safety of buildings within this area would be influenced by the train-induced vibrations of the metro system. and thus attention should be paid to this problem.
