The　standard　k-Ε　turbulence　model　was　adopted　to　simulate　smoke　flow　in　three-dimensional　station　with　island-platform　and　side-platform　with　platform　screen　door　system　on　different　fire　scenes.　The　simulation　results　show　that　the　chimney　effect　is　significant　and　become　a　smoke　mouth　near　the　stairs　when　fire　took　place　in　subway　side-platform;　the　smoke　is　mainly　expanded　the　sides　of　tunnel　when　fire　occurred　in　subway　island-platform;　The　screen　door　system　act　the　role　of　counterwork　on　the　transfer　of　heat　and　obstruct　from　smoke　spread,　and　it　is　key　to　safety　evacuate　for　persons　in　hybrid　station.
