According　to　the　Cross-structure　between　subway　station　and　tunnel　in　formation　condition　of　silt　sand　in　Beijing,　a　series　of　shaking　table　tests　on　the　dynamic　interaction　between　soil　and　structure　are　carried　out.　In　the　case　of　inputting　waves,　monitor　the　acceleration,　displacement　of　soil,　the　acceleration,　strain　of　structure　and　dynamic　earth　pressure　between　soil　and　structure.　Research　on　the　seismic　force　and　deformation　characteristics　of　station,　and　analyzed　the　interaction　law　of　seismic　response　of　Cross-structure　of　subway　station　and　tunnel.　The　result　shows　that　the　top　displacement　of　model　box　is　larger　than　the　bottom,　and　the　distribution　law　of　the　acceleration　is　contrary.　The　acceleration　response　of　shallow　soil　is　weakened　with　the　structure　buried.　The　interaction　force　between　soil　and　structure　is　comparatively　large.　The　strains　of　columns　and　walls　are　larger　than　which　of　beams　and　plates.　Stress　concentration　is　generated　on　the　joints.　The　bottom　tunnel　can　absorb　the　earthquake　waves　coming　from　shaking　table　test,　and　reduce　the　seismic　response　of　the　upper　station　structure.　The　week　effect　reduces　with　soil　thickness　increasing.
