This　paper　used　＂FDS+Evac＂　simulation　model　to　analyze　the　platform　transfer　area　fire　scene.　It　focused　on　the　effect　of　the　interaction　between　the　fire　and　personnel　evacuation　on　the　result　of　evacuation.　Through　the　analysis　of　evacuation　with　fire　or　without　fire　and　fire　scene　in　different　conditions,　the　important　influence　of　the　fire　smoke　to　evacuation　personnel　psychological　and　physiological　aspects　was　obtained.　Results　have　shown　that　effect　of　fire　environment　on　evacuation　is　significant,　mainly　reflected　in　the　following　three　aspects:　extending　the　evacuation　time,　limiting　the　scope　of　activities　and　changing　the　personnel　evacuation　route.　The　results　of　this　study　will　help　guide　the　evacuation　design　of　underground　space　on　fire　situation.　(C)　2017　The　Authors.　Published　by　Elsevier　Ltd.
