Underground　complex　with　transport　hub　can　effectively　relieve　the　urban　traffic　pressure　and　expand　urban　capacity,　which　is　booming　now　in　China.　however,　the　space　layout　and　diversification　of　its　function　pose　the　difficult　on　the　emergency　evacuation　and　path　recognition.　In　addition,　with　a　large　number　of　people　as　the　heavy　fire　load,　an　unsuccessful　design　will　cause　great　casualties　and　property　losses.　At　present,　for　there　is　a　lack　of　referential　standard　and　the　domestic　researches　still　lag　behind　the　existing　condition,　it　is　urgent　to　carry　out　related　research.　Firstly,　this　essay　discusses　types　and　characteristics　of　underground　complex　with　transport　hub,　and　analyses　evacuation　difficulties　and　key　factors　in　successful　evacuation.　Secondly,　with　the　aim　of　improving　the　space　recognition　and　path-finding　efficiency,　this　essay　divides　the　underground　space　into　three　different　levels　(whole,　zone　and　unit),　and　puts　forward　a　series　of　plans　for　the　space　layout,　design　elements,　and　the　index　for　the　horizontal　and　vertical　evacuation　space.　The　evacuation　design　for　whole　level　can　be　carried　out　by　three　ways.　Taking　the　city　planning　and　city　disaster　prevention　into　consideration,　the　UCTH　should　build　a　harmonious　relationship　with　the　ground　buildings,　transportation,　public　green　space;　Combined　with　its　function　and　internal　transportation,　the　whole　underground　space　should　be　divided　into　several　evacuation　partitions;　design　emergence　shelter,　which　is　separated　from　other　zones　by　firewall　so　that　it　can　protect　people　from　fire　or　explosion.　The　evacuation　design　for　zones　mainly　focused　on　commercial　zone　and　transport　hub　zone.　Which　should　taking　the　function　and　spatial　relationship　into　consideration　as　well　as　take　evacuees＇　behavior　and　psychological　in　consideration.　Atrium　or　sinking　square　would　contribute　to　a　successful　evacuation.　The　evacuation　design　for　units　could　be　done　from　by　Horizontal　evacuation　design　and　Vertical　evacuation　design.　For　Horizontal　evacuation　design,　fire　and　smoke　prevention　units　are　necessary.　The　overall　layout　should　meet　requirements　for　horizontal　evacuation　route.　Evacuation　index　such　as　the　number　of　safety　stairs　and　fire　elevators,　the　horizontal　evacuation　distance　should　be　set　appropriately.　Vertical　evacuation　design　consists　of　appropriate　location　and　form　of　vertical　evacuation　route.　Vertical　transport　in　nodes　should　be　paid　special　attention　and　vertical　fire　prevention　units　as　well　as　smoke-proof　units　in　atrium　are　also　required.　The　paper　will　provide　good　references　for　a　perfect　evacuation　system　of　underground　complexes　with　transport　hub　and　the　establishment　of　related　design　standards.
