近年来随着地下商业建筑的增多,消防安全问题也受到广泛关注。地下商业建筑日常客流量大,火灾救援难度大,且火势蔓延快,烟气重,因而消防安全疏散设计应注意防火分区设置,尽量缩短疏散通道的距离,保证足够的安全出口。同时为有效控制烟气,地下商业建筑应科学划分防烟分区,选用适合的排烟方式,并设立相应的排烟口。 In recent years, with the increase of underground commercial buildings, fire safety issues have also received widespread attention. Underground commercial buildings daily traffic, fire rescue difficult, and the spread of fire fast, heavy flue gas, fire safety evacuation design should pay attention to the fire district set to minimize evacuation routes distance to ensure adequate safety exit. At the same time to effectively control the flue gas, underground commercial buildings should be divided into scientific division of smoke, use the appropriate exhaust mode, and set up the corresponding exhaust port.
