摘　　要：为研究位于某广场建筑商业综合体裙房中央的下沉式广场作为人员疏散的准安全区的可行性,运用烟气模拟软件FDS得到了可用安全疏散时间ASET,并通过疏散模拟软件Building-Exo-dus和水力模型计算方法得出了所需安全疏散时间RSET。研究表明,人员安全疏散条件ASET<RSET能够得到满足,因而该中央下沉式广场可以作为人员疏散的准安全区。In order to study the feasibility of a sunken plaza used for relative security zone when it is located in the center of a square＇s commercial podium,the available safety egress time was acquired by numerical simulations which were carried out by FDS,then the required safety egress time was obtained by hydraulic model calculation and numerical simulations that were carried out by Building-Exodus.Comparing the data,it indicated that the condition ASETRSET ensuring safety evacuation could be satisfied,therefore,the sunken plaza can be used for relative security zone.
