摘要
从地下建筑火灾特性出发，提出了地下建筑火灾中的火烟运动模式及其沿地下巷道运动的火烟温度、火风压沿程变化规律，同时分析了火烟与防火隔烟水幕相互作用特性，最后依据我国地下建筑防火规范，提出了防火隔烟水幕在地下建筑中的应用。
In the light of the characteristics of the fire in underground structures,the paper presents a model of the smoke movement during the structures on fire and investigates the rules offluctuation of the smoke temperature and overfire draft along underground lanes. Characteristics of interaction between smoke and the water screen for fire-prevention and smoke-insulationis analyses. In accordance with the fire regulations of our country about underground structures,the paper finally discusses the application of such a water screen in underground structures.
