地下空间因具有对外出口少、空间相对封闭、通风口面积小、自然排烟困难等特点,使其内一旦发生火灾,将极有可能造成严重的后果。通过文献调研与分析,从火灾场景、结构抗火、火灾预警及消防系统、疏散逃生等方面对国内外地下空间防火安全的研究状况进行了总结与介绍。最后,对于地下空间防火安全的研究方向进行了展望。 Underground space due to less external exports, space is relatively closed, the vent area is small, natural smoke exhaust and other characteristics, to make it a fire, it will most likely have serious consequences. Through the literature research and analysis, the research status of fire safety in underground space at home and abroad are summarized and summarized from the aspects of fire scene, structure fire resistance, fire early warning and fire fighting system, evacuation and escape. Finally, the research direction of fire safety in underground space is prospected.
