By Using ABAQUS finite-element software and considering the influence of soil-structure interaction
the nonlinear dynamic soil-metro tunnel interaction is modeled.Seismic response of the circular and straight-wall-top-arch tunnel is numerical analyzed
the stresses
acceleration responses and relative horizontal displacements of the tunnel with the same field condition and buried depth are obtained.The computation results prove that stress and relative horizontal displacement response of circular tunnel are less than that of straight-wall-top-arch tunnel
hence circular-shaped tunnel should be considered as a priority.
