Based　on　a　large-scale　shaking　table　test　of　typical　subway　station　in　Beijing　Region,　A　continuum-discrete　element　coupled　model　was　built　to　simulate　the　seismic　responses　and　the　damage　process　of　subway　station　structure　model.　In　the　coupling　model,　the　soil　was　simulated　by　continuaus　model,　and　the　structure　was　simulated　by　particle　flow　discrete　model.　Interfaces　are　built　on　the　boundary　nodes　of　FLAC　and　used　as　walls　in　PFC.　Displacements　calculated　by　FLAC　in　large-strain　model　were　transfered　to　PFC　through　interfaces,　and　the　interaction　force　between　particle　and　interfaces　was　transfer　to　FLAC　as　the　force　acted　on　nodes　to　realize　the　parallel　coupling　calculation.　The　results　show　that　the　calculated　results　are　in　good　accordance　with　experimental　ones.　The　nodes　of　column-plate　and　wall-plate　are　weak　parts　of　subway　station　structure　model　during　inputting　earthquake　waves.　The　whole　damage　process　and　energy　conversion　process　of　structure　model　can　be　divided　into　three　phases.　The　change　of　porosity,　average　number　of　contacts　and　contact　force　and　the　energy　conversion　law　can　reflect　the　damage　process　of　structure.
