摘　　要：采用性能化防火设计思想,分析老山自行车馆大厅的排烟系统所应达到的安全目标,设计了可能发生的火灾场景,使用CFD技术研究自然排烟系统的性能,通过数值模拟给出发生火灾时的流场和温度分布,证实大厅自然排烟系统能够保证人员安全疏散,满足该建筑消防安全要求。In this paper, performance-based fire safety design concept was adopted to analyze the fire safety objective that the smoke evacuation system of Laoshan bicycle racing centre should achieve, fire scenarios were designed and the performance of natural smoke evacuation system was studied by using CFD techniques. The velocity and temperature distributions during the fire was obtained by using numerical simulation method, the fact that people in the centre could be evacuated safely was proved and the building＇s fire safety objective was satisfied.
