With　the　development　of　the　Chinese　economy　and　society,　the　height　and　density　of　urban　buildings　are　increasing,　and　large　underground　transportation　hubs　have　been　constructed　in　many　places　to　alleviate　the　pressure　of　transportation.　Commercial　buildings　are　usually　developed　above　the　large　underground　transportation　hubs,　so　the　underground　structures　may　have　very　shallow　depths　or　no　soil　cover.　The　seismic　response　and　damage　mechanisms　of　such　underground　structures　still　need　to　be　studied.　In　this　paper,　an　example　of　a　project　in　China　is　taken　as　an　object　to　analyze　the　seismic　response　and　damage　mechanism　of　the　structure　after　simplification.　The　spatial　distribution　of　deformations　and　internal　forces　of　such　structures　and　the　location　of　the　maximum　internal　forces　are　obtained,　and　the　effect　of　the　frequency　of　seismic　motions　on　the　structural　response　is　obtained.　Finally,　an　elastoplastic　analysis　of　such　structures　is　carried　out　to　assess　the　damage　location　and　the　damage　evolution　process.
