Strength and deformation of soil around the subway tunnel is greatly affected by the vibration induced by the subway trains. In this paper, taking Beijing subway line 5 as an example, the dynamic responses of subway tunnels with rectangular and circular sections under train’s vibration loading are computed by means of the finite element code. The deformation of soil around the subway tunnels and the displacements of the ground surface are also given. The computation results for the two sections are analyzed and compared mutually. These results may provide some reference data for subway tunnel design。
