A　shaking　table　experiment　was　conducted　on　a　shield-enlarge-dig　type　subway　station　structure　in　sandy　ground　subjected　to　the　near　field　earthquake　and　the　far　field　earthquake.　The　horizontal　displacement,　surface　deformation,　acceleration,　earth　pressure　response　of　the　model　ground　and　the　acceleration　and　strain　of　the　model　structure　of　sandy　soil　are　analyzed.　The　measured　data　substantiate　that,　the　seismic　response　of　soil-structure　interaction　system　is　more　intense　to　the　ground　motion　with　low-and　medium　frequency.　The　subway　station　structure　subjected　to　strong　earthquake　motions　has　obvious　spatial　effect,　and　the　existence　of　underground　structure　will　result　in　a　change　in　the　deformation　distribution　mode　of　ground　surface.　The　acceleration　response　of　columns　of　the　model　structure　increases　gradually　from　bottom　to　top　as　result　of　a　low-intensity　earthquake,　while　for　the　high-intensity　earthquake,　the　acceleration　response　presents　a　law　of　increasing　first　and　then　decreasing.　The　acceleration　response　of　the　top　plate　is　the　biggest,　followed　by　middle　plate　and　bottom　plate　is　the　smallest　under　seismic　action.　And　in　addition　to　this,　the　acceleration　response　of　the　model　structure　is　roughly　equal　to　that　of　the　model　soil,　and　the　dynamic　earth　pressure　of　the　side　wall　increases　gradually　from　bottom　to　top　as　result　of　the　low-intensity　earthquake;　while　for　the　high-intensity　earthquake,　the　acceleration　response　of　the　model　structure　significantly　surpasses　that　of　the　model　soil,　and　the　maximum　value　of　earth　pressure　occurs　at　the　arch　shoulder　and　the　middle　part　of　the　expanded　tunnel.　The　earthquake　damage　mechanism　of　the　shield-enlarge-dig　type　subway　station　structure　is　given　based　on　the　macroscopic　phenomena　of　model　structure　after　shock　and　the　stretching　strain　amplitude　under　different　ground　motions.
