A field test was performed in the subway tunnel of metro Line 1 at Shanghai People’s Square Station. According to the data of the track acceleration test and the equation of the vehicle system vibration，a simulated deterministic expression of the metro load was obtained.The ground vibration due to the moving metro was simulated by applying the load to an FLAC3D numerical model. Through comparison of the numerical analysis results of different working conditions, the wave propagation, and attenuation at the ground surface, the dependence of the ground vibration on the tunnel depth and the frequency of the simple harmonic excitation load are analyzed.
