As　urban　rail　transit　progresses,　subway　stations　must　serve　not　just　as　transportation　hubs　but　also　fulfill　additional　urban　functions.　Integrated　underground　stations　aim　for　intensive　development,　considering　subway　stations　and　their　surrounding　subterranean　structures　as　a　whole,　with　unified　design　and　construction.　This　approach　enhanced　resource　utilization　and　socio-economic　benefits.　Seismic　environments　of　varying　frequencies　and　amplitudes　(0.1g　to　0.5g)　were　simulated　using　waveforms　recorded　during　the　Wenchuan　earthquake　(main　frequency　15.9　Hz),　the　Tangshan　earthquake　at　Beijing　Hotel　(main　frequency　0.7　Hz),　and　artificial　waves　(main　frequency　5.2　Hz)　provided　by　a　construction　site　safety　assessment　report.　Large-scale　shake　table　tests　were　conducted　to　assess　the　seismic　response　of　integrated　underground　subway　station　structures　under　different　frequencies　and　peak　ground　accelerations　(PGAs).　The　results　are　drawn　as　follows.　The　subsidence　of　the　soil　on　both　sides　of　the　station　structure　and　damage　at　the　soil-structure　interface.　Soil　acceleration　response　sensitivity　to　the　Beijing　Hotel　wave　increases　with　PGA.　With　PGA=0.3g　as　a　threshold,　the　influence　of　the　Beijing　Hotel　wave　on　the　station　structure　is　minor　when　PGA0.3g.　Regarding　the　strain　amplitude　in　the　station　structure’s　columns,　the　top　of　the　negative　first-floor　middle　column　registers　the　highest　strain　amplitude.　The　bottom　of　the　negative　third-floor　middle　column　had　the　highest　strain　amplitude.　Conclusions　are　as　follows.　(1)　The　soil-structure　interface,　where　material　stiffness　changes　abruptly,　is　prone　to　damage　due　to　the　softer　soil.　(2)　Under　low-frequency　wave　influence,　the　seismic　response　of　the　model　system　increases　with　PGA.　(3)　The　top　of　the　negative　first-floor　middle　column　and　the　bottom　of　the　negative　third-floor　middle　column　are　the　most　vulnerable　to　seismic　activity.　It　is　recommended　that　integrated　underground　subway　stations　prioritize　seismic　performance　optimization　at　these　locations　during　design　and　construction,　especially　in　areas　of　high　seismic　activity.　©　2024,　Central　South　University　Press.　All　rights　reserved.
