Subway　stations　are　important　means　of　transportation　and　main　targets　attacked　by　terrorists.　In　order　to　study　the　subway　station　response　and　damage　subjected　to　blast　loading,　numerical　simulation　is　carried　out　to　estimate　a　subway　station　in　beijing.　An　“explosive-air-structure　”　dynamic　interactive　numerical　model　is　built　for　the　blast　dynamic　analysis　of　subway　station　subjected　to　blast.　The　patterns　of　damage　about　column　are　compared　in　different　charges　of　explosive.　The　damages　of　concrete　and　reforcing　bar　in　column　are　discussed.　Although　the　column　near　the　explosive　is　destoried　under　the　charge　of　30kg　TNT,　The　calculations　showns　that　it’s　safe　for　the　subway　station　to　subject　to　blast　loading　under　the　charge　of　30kg　TNT.　The　local　damage　of　column　influence　collapse　of　the　station　little.　The　dynamtic　response　of　the　structure　is　given　to　support　the　protection　on　the　subway　station　against　terrorism　bombing.　©　Qiushi　Yan;　Licensee　Bentham　Open.
