青奥体育馆人员疏散设计性能化评估

Performance-based assessment of people evacuation design in Youth Olympic Stadium

以青奥体育馆为研究对象,针对建筑消防设计中防火分区面积、疏散距离因功能需要远远超出国家现行消防技术规范的常见问题,采取控制火灾荷载、加强防火分隔、完善消防设施等强化措施,并采用消防安全性能化评估方法评估方案的安全性。建立火灾模型,对烟气蔓延和人员疏散进行模拟计算,结果表明,现有的设计方案能够在火灾时保证人员的安全疏散。

Based on Youth Olympic Statium, fire design problems as over-large area of fire apartment and over-long evacuation distance were analyzed, the countermeasures were proposed as controlling fire load, strengthening fire separation and improving fire facilities, and performance-based assessment method was used. Set fire mode, simulate smoke spread and evacuation. The results showed that the existing fire design could assure people safety in fire.
