摘　　要：为合理设计地下多层体育馆的防排烟系统,提高体育馆防火安全性,采用计算流体力学方法和消防性能化分析,结合建筑的使用用途和特点,设定典型火灾场景开展数值仿真,针对该类体育文化馆消防设计方案中建筑防火分区面积超过规范限值要求的情况,研究优化后消防设计方案能否满足消防安全目标,并验证该方案的可靠性。结果表明:优化后各火灾场景下的防排烟系统可维持人员相对安全的水平,并有一定的安全余量,可达到国家防火技术标准的同等水平。In order to design the smoke control system of a gymnasium with multi-storey of basements reasonably,the computational fluid dynamics method was used to analyze and demonstrate the performance-based fire protection by setting up a typical fire scenario in combination with the use and characteristics of the building when the area of the building's fire compartment in the fire protection design scheme of a gym exceeded the requirements of the specification.According to the demonstration results,the optimized fire protection design scheme is proposed to ensure that the building fire protection design scheme meets the fire safety objectives.Through the fire smoke simulation and personnel safety evacuation simulation of the optimized building fire protection design scheme,there liability of the optimized fire protection design scheme is verified.Result shows that the optimized smoke exhaust system of each fire scenario can maintain the safety environment for personnel to escape,and has a certain safety margin,which can reach the same level as the national fire prevention technical standard.
