地下空间防火安全研究概述

Overview of fire protection safety research in underground space

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。

Fire hazard is a big threat to safety in underground space due to its characteristics of limited exits,relatively closed space,small vet areas and difficultly in smoke ejecting.Based on literature investigation and analysis,research about fire safety in underground space at home and abroad were summarized in categories of fire scene,structural fire resistance,fire alarm,fire fighting system and evacuation.At last,the suggestions on further research are presented.
