摘要
大型剧场类建筑人员疏散消防设计往往存在疏散距离过长的设计难点。本文基于性能化防火设计的思想,对某剧场类建筑设计中存在的疏散距离过长的问题进行分析,并分别对前厅、舞台和观众厅区域提出设置亚安全区、隔离火源和增加蓄烟空间等建议措施。结合数值模拟Pathfinder软件,对该剧场内部建筑结构及人员荷载进行详细分析,共设置了5个不同起火位置、不同疏散模式的火灾场景。分析人员疏散模拟结果,通过各不同火灾场景下人员疏散时间来评估人员疏散的安全性,得出在各种不同火灾场景中人员皆可安全疏散的结论,并提出了保证该剧场类建筑消防安全的强化措施和建议。
The evacuation design of the large theatre buildings is often facde up with design problems of long evacuation distance.Based on the method of performance-based fire protection design,we carried out analyses on the problem of long evacuation distance in this paper and proposed some measures for the lobby,stage and auditorium area,such as set up an sub-safely zone,isolate sources of ignition and increasing smoke storage space.Analysis of the theater's internal building structure and personnel load,set a total of five different fire location and different evacuation modes of the fire scene;The evacuation of the large theatre building was simulated and the time for evacuation was obtained using the simulation software Pathfinder.Analysts evacuate the simulation results,through the evacuation time of personnel in different fire scenes to assess the evacuation safety of personnel,come to the conclusion that the evacuation of personnel in all kinds of different fire scenes can be safely evacuated and some measures and suggestions were given to insure fire safety on the theatre building.
