针对IMAX影厅面积普遍超过规范要求、火灾危险性大和人员疏散困难等因素,选取大型商业综合体的IMAX影厅为研究对象,在影厅及附近公共走道部分设计为独立防火分区,影厅内喷淋有效、排烟有效的条件下,采用FDS和STEPS软件进行厅内火灾模拟和人员疏散模拟.结果表明,影厅内烟气不会蔓延至走道等公共区域,环境未达到人员耐受极限,人员能安全疏散至公共区域,安全余量时间较大有利于消防队员的扑救和财产转移. In view of the fact that the IMAX auditorium area generally exceeds the regulatory requirements, the fire danger is large and the evacuation of staff is difficult, the IMAX auditorium of a large commercial complex is chosen as the research object and is designed as an independent fire precinct in the auditorium and nearby public walkways. Spraying effective, smoke exhaust effective conditions, the use of FDS and STEPS software simulation of fire and personnel evacuation simulation results show that the shadow of the hall will not spread to walkways and other public areas, the environment did not meet the limits of personnel tolerance , Personnel can be safely evacuated to public areas, safety margin greater time is conducive to firefighters fighting and property transfer.
