大型体育场因其空间巨大,容纳观众几万到几十万人,存在一定的人员疏散危险性,本文针对某容纳3.5万人的开敞式体育场开展人员疏散数值模拟计算研究,基于性能化设计方法,采用疏散软件Building Exodus进行人员疏散模拟计算,模拟结果显示尽管人员疏散完毕时间为353s,超过我国《建筑设计防火规范》中要求的体育馆内人员疏散时间在4分钟内的限制,但对于开敞式体育场,其火灾危险性较小,人员疏散时间可适当延长,在制定疏散策略时,可采用综合性疏散策略,包括在入场票面上加注详细的疏散路线,辅以语音广播系统等提高人员疏散效率。
Because of its huge space, large stadiums can accommodate tens of thousands to tens of thousands of spectators, there is a certain danger of personnel evacuation. In this paper, a 35,000-person open stadium for personnel evacuation numerical simulation study, based on the performance-based design method , The evacuation simulation software Building Exodus was used to simulate the personnel evacuation. The simulation results showed that although the evacuation completion time was 353s, exceeding the limit of 4 minutes for the evacuation time of the gymnasium required by the Code for Fire Protection of Building Design in our country, Stadiums, the fire risk is small, the evacuation time may be appropriately extended, evacuation strategy in the development, the use of a comprehensive evacuation strategy, including the ticket entry in the face of detailed evacuation routes, combined with the voice broadcast system to improve Personnel evacuation efficiency.
