地下商业建筑安全出口设计时会遇到很多的消防设计难题,典型的疏散难题包括疏散距离过长和疏散宽度不足。本文针对以上消防设计问题开展数值模拟研究,结果表明相对于烟气层温度,能见度对地下商业区的影响更为明显。因此对于地下商业区,必须加强防排烟设施的消防检查和火灾隐患排查工作,以保证火灾条件下人员的生命安全。
Underground commercial building safety exit design will encounter many fire design problems, the typical evacuation problems include the evacuation distance is too long and the evacuation width is insufficient. In this paper, a numerical simulation study on the above fire protection design problems is carried out. The results show that the visibility has an obvious influence on the underground commercial area relative to the flue gas layer temperature. Therefore, for underground commercial areas, fire inspection and investigation of fire hazards in smoke control facilities must be strengthened to ensure the safety of personnel under fire conditions.
