高校图书馆消防安全疏散数值分析

以国内某高校图书馆为实例,利用FDS和Pathfinder对该图书馆进行火灾及人员疏散全尺寸模拟。研究图书馆发生火灾时烟气扩散、温度分布及能见度对人员逃生的影响。主要方法为通过火灾模拟软件FDS模拟分析发生火灾时的可用安全疏散时间(ASET),并使用疏散模拟软件PathFinder计算所需安全疏散时间(RSET),进而判断图书馆目前管理状况是否满足火灾时的人员安全疏散需要。结论表明:该图书馆目前管理状况不能满足火灾条件下人员逃生的需要,而影响人员安全疏散的主要因素为烟气的扩散。在研究结果的基础上提出改进建议,为图书馆日后的管理及灭火救援提供理论依据。

College libraries fire safety evacuation numerical analysis

Having a university library in domestic as the example,FDS and Pathfinder are used to make a full size simulation of the library＇s fire and evacuation.The flue gas diffusion,the temperature distribution and the influence of visibility on personnel escape are researched when the library is on fire.The main method is simulating and analyzing the available safe evacuation time（available ASET） through the fire simulation software FDS and using evacuation simulation software PathFinder to calculate the required safety evacuation time（RSET）,and then judge whether it meets the need of staffs escape when the library is on fire.The conclusion shows that： the library can＇t meet the need of staffs escape when it is on fire in its daily management situation,and the biggest obstacle to the safe evacuation of staffs is the foreground＇s visibility.So recommendations are made on the basis of the research result,which provides theoretical basis to the library＇s management and rescue work in the future.
