摘　　要：在设定火灾条件下,基于FDS模拟得到的可用疏散时间,利用相对应的疏散场景和构建的Path Finder疏散模型,开展展览大厅和展览小厅的人员疏散模拟研究.在选择案例展览大厅和展览小厅的使用人数分别设计为6 750(6 600)人、2 450人的前提下,研究结果表明:在对应疏散场景分别为展览大厅通过疏散出口、展览小厅通过疏散出口直接疏散到室外、展览小厅通过疏散出口直接疏散到室外或相邻分区的条件下,设定火灾场景是为自动喷水灭火系统失效、机械排烟系统开启,人员必需疏散时间分别为510、455和543 s,人员可用疏散时间分别为不小于1 200 s,均满足T_(RSET)<T_(ASET).设定火灾场景是自动喷水灭火系统将火灾最大热释放速率控制在2.2 MW、机械排烟系统开启,人员必需疏散时间分别为510、455和543 s,人员可用疏散时间分别为不小于1 140 s,均满足T_(RSET)<T_(ASET).在设定火灾场景条件下,设计的安全出口能满足人员安全疏散需要.Under the set fire conditions,based on the available evacuation time obtained from FDS simulation,a simulation study of personnel evacuation in exhibition halls and small exhibition halls was conducted using the corresponding evacuation scenarios and the constructed Path Finder evacuation model.Under the premise of designing the number of users for the exhibition hall and exhibition small hall as 6 750 (6 600) and 2 450people respectively,the research results show that in the corresponding evacuation scenarios,the exhibition hall is directly evacuated to the outside through evacuation exits,the exhibition small hall is directly evacuated to the outside through evacuation exits,and the exhibition small hall is directly evacuated to the outside or adjacent zones through evacuation exits.If the fire scenario is set as automatic sprinkler system failure and mechanical smoke exhaust system activation,the necessary evacuation time for personnel is 510,455,and 543 s,and the available evacuation time for personnel is not less than 1 200 s,T_(RSET)<T_(ASET).If the fire scenario is set as an automatic sprinkler fire extinguishing system,with the maximum heat release rate controlled at 2.2 MW and the mechanical smoke exhaust system turned on,the necessary evacuation time for personnel is 510,455,and 543 s,respectively.The available evacuation time for personnel is not less than 1 140 s,and T_(RSET)<T_(ASET).Under the conditions of setting fire scenarios,the designed safety exits can meet the needs of safe evacuation of personnel.
