基于对地下深层空间的充分合理利用,本文全面探讨了地下深层商场防火设计的关键参数,并利用性能化防火分析的方法,对某地下3层商场在设定火灾条件下的人员疏散安全性进行了研究。结果表明,通过设置水平方向直通室外的疏散通道,在保障消防系统正常工作的情况下,能够保证人员安全疏散,故将地下3层作为商场是可行的。
Based on the full and rational utilization of underground deep space, this paper comprehensively explores the key parameters of the fire prevention and design of the underground shopping arcades. By using the method of performance fire analysis, the evacuation safety of a 3-storey underground shopping mall under the set fire conditions Study. The results show that it is feasible to set the underground 3 storeys as a shopping mall by setting up an evacuation passage in the horizontal direction through which the outdoor can be evacuated while ensuring the normal operation of the fire protection system.
