摘要：

Based　on　the　shaking　table　test　result　of　the　dynamic　interaction　between　soil　and　subway　tunnel　in　liquefiable　soil,　a　2-D　nonlinear　dynamic　interaction　finite　element　model　is　established　to　simulate　the　system　of　soil-tunnel　with　the　platform　of　ABAQUS.　In　the　finite　element　model,　dynamic　viscoplastic　model　with　memorial　nested　yield　surface　is　used　to　simulate　the　dynamic　characteristic　of　soil,　while　the　plastic-damage　model　is　used　to　simulate　the　dynamic　characteristic　of　concrete.　Corresponding　to　the　test　conditions,　all　the　instances　are　simulated.　Compared　with　the　test　record,　it　is　proved　that　both　the　finite　element　model　and　the　shaking　table　test　are　correct,　their　results　are　well　identical　with　each　other＇s　and　the　rules　are　coincident　as　well.
