摘要：

A　large-scale　shaking　table　test　for　subway　station　structure　built　in　the　liquefiable　saturated　fine　sand　soil　is　implemented.　Partial　test　results　are　analyzed　in　this　paper.　The　acceleration　time-histories　and　the　dynamic　pore　water　pressure　ratio　time-histories　of　ground　soils　are　given.　During　the　whole　process　of　testing,　it　is　obvious　that　the　soils　at　the　top　of　model　ground　and　beside　the　subway　station　structure　is　liquefied　firstly.　Then　the　soil　far　from　the　subway　station　structure　and　at　the　bottom　of　model　ground　is　liquefied　with　the　increasing　of　the　peak　value　of　acceleration　inputted　by　the　surface　of　shaking　table.　However,　the　soils　under　the　subway　station　structure　is　not　liquefied　during　the　whole　process　of　testing.　At　the　same　time,　the　subway　station　structure　uplifts　badly　during　the　soil　liquefaction.
