Abstract Based on the software ABAQUS 64 CPU explicit parallel computing cluster platform, taking underground structures near Nanjing metro line 4 drum tower station as the background, a 3D refined finite element model was built for a deep soft soil-subway tunnel-civil air defense basement coupled system to numerically simulate its seismic responses underexcitations of near-field Wenchuang earthquake Qingping wave, far-field Mexico one and Nanjing artificial seismic one with the exceedance probability of 3% within 100 years, respectively. The results showed that the damage value of the place near “penta-centric circle” tunnel’s spandrel and haunch arc joint is the maximum, plastic deformation produced causes sudden changes to appear on the structural relative displacement curve; the damage level is the most serious at roof and floor of basement, top and bottom of side wall, especially, basement turning place, the rest places are safer; the relative displacement curve of civil air defense basement is smooth and it monotonically rises along the height; compared with the tunnel, though damage values of civil air defense basement’s local areas are slightly larger, their relative displacements are smaller; civil air defense basement causes damage values of tunnel’s local areas to slightly increase while the range of large relative displacement obviously decreases; the influence of tunnel on civil air defense basement has no obvious law.
