图书馆安全疏散数值分析

摘要

Taking a university library in China as an example, a full-size evacuation of library is simulated by FDS and FDS + EVAC. The key validation is whether the status of management of the library fire can meet the requirements of the safety of e-vacuation and a reasonable improvement program. The conclusions are: The current management situation of the library can not meet the personnel need to escape under fire and the main factor affecting the safety of evacuation is fire visibility. A optimization was obtained by experimental analysis, it is recommended that the left secure channels on the third, fourth, sixth and seventh floors should be open in future management, and responsible persons should be arranged to open the second and fifth floors' secure channels as well as library's two side entrances timely in the fire to ensure the safe evacuation of person.%以国内某高校图书馆为例,使用火灾模拟软件FDS和安全疏散软件FDS+ EVAC对图书馆火灾时的安全疏散进行全尺寸模拟,验证火灾时图书馆的管理现状能否满足人员安全疏散的要求,并提出改进方案.模拟结果表明: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火场能见度.通过实验分析获取的优化方案为:建议在以后的管理中增开左侧三、四、六、七楼的安全通道,同时应安排专人负责在火灾时及时打开二、五楼的安全通道及图书馆两侧门以保证人员的安全疏散.
