A　shaking　table　experiment　was　conducted　on　a　shield-enlarge-dig　type　structure　in　liquefiable　ground　subjected　to　the　near　and　far　field　earthquakes　respectively.　The　lateral　deformation,　the　pore　pressure　ratio,　the　earth　pressure　of　soil　foundation,　the　accelerations　of　soil　and　structure　and　the　strains　of　structure　of　subway　station　were　analyzed.　The　results　showed　that　liquefiable　foundation　experienced　two　physical　process　in　earthquake,　the　loose　sand　compacted　firstly　and　then　moved　upwardly.　There　were　phenomena　of　sand　erupting　and　water　oozing　in　large　area　after　the　high　intensity　earthquake.　The　shear　deformation　occurred　in　the　lateral　side　of　the　soil　and　the　peak　displacements　swing　left　and　right　asymmetrically.　The　acceleration　amplification　factor　of　soil　foundation　increased　gradually　from　the　bottom　to　the　surface　when　the　small　earthquake(peak　acceleration　was　0.1　g　and　0.2　g)　was　input　while　it　showed　an　increasing　trend　when　a　moderate　or　strong　earthquake　was　input　from　the　shaking　table.　A　notable　phenomenon　of　high　frequency　filtering　and　low　frequency　amplification　appeared　in　the　process　of　seismic　wave　propagation　from　the　bottom　to　the　surface　of　soil.　The　pore　water　pressure　experienced　mainly　two　stages,　the　pore　water　pressure　increased　slowly　at　first,　rose　sharply　then　at　the　second　stage.　The　existence　of　the　underground　structure　has　an　inhibitory　effect　on　the　growth　of　the　pore　water　pressure　of　foundation.　The　earth　pressure　increased　and　the　structure　itself　in　the　elastic　state　entered　into　the　plastic　state　gradually　with　the　increase　of　input　vibration　intensity.　The　difference　between　the　upper　and　lower　ground　pressures　of　the　underground　structure　was　the　intrinsic　factor　that　caused　the　model　structure　to　generate　an　upward　movement.　The　earthquake　damage　of　the　underground　subway　station　of　shield-enlarge-dig　type　in　liquefiable　ground　experienced　three　stages:　firstly,　a　shear　failure　occurred　on　the　column　and　a　damage　on　the　opening　position　and　spandrel　of　the　tunnel;secondly,　the　connection　parts　of　the　side　wall　and　roof　had　the　tensile　damage;finally,　the　underground　structure　collapsed.　©　2017,　Science　Press.　All　right　reserved.
