The　soil-structure　finite　element　model　of　DAIKAI　subway　station　damaged　in　1995　kobe　earthquake　was　built　by　two　dimensional　plane　strain　element,　in　full　accordance　with　the　actual　structure　size　and　ground　information　of　DAIKAI　subway　station.　Both　dynamical　response　and　damage　process　of　DAIKAI　subway　station　were　simulated　based　on　XN　and　UD　acceteration　time　histories　recorded　at　83　m　underground　in　port　istand　in　kobe　earthquake,　while　dynamical　non-linearity　was　considered　by　both　equivalent　damp　and　equivalent　shear　modulus　of　soil　inthe　earthquake.　The　damage　mechanism　of　DAIKAI　subway　station　in　the　earthquake　was　studied.　The　damage　types　of　middle　column,　side　wall　and　roof　were　analyzed.
