摘要
在地下建筑灭火实战中,排除烟尘是救援人员进入火场顺利地进行侦查、救援、疏散和灭火的前提保证。本文通过研究了地下建筑的火灾的烟气流动特性、地下建筑火灾蔓延特点及排烟的重要性、研究了各种排烟策略。本文采用美国国家标准和技术研究院(NIST)开发的FDS(Fire Dynamic Simulator)软件,建立地下建筑模型,对地下火灾进行全尺寸模拟。通过模拟实验比较不同环境下三种排烟策略的排烟效果,为地下建筑火灾决策提供有力的依据。
Underground building fire, Rule out the smoke is smooth rescue workers to enter the fire investigation, rescue, evacuation and fire the premise that. This paper studies the underground construction of the flue gas flow characteristics of fire, fire spread underground construction characteristics and the importance of smoke, smoke of a variety of strategies. In this paper, NIST developed the FDS software. Establishment of underground construction model, the full scale underground fires. By comparing different simulation strategies under the three exhaust smoke effect, an underground building fire provide a strong basis for decision-making.
