摘要
高校图书馆具有高易燃和人口密度大的特点,一旦发生火灾会引起严重的校园连锁效应,对高校图书馆火灾疏散的研究很有必要.首先,通过文献汇总,梳理图书馆火灾疏散的影响因素;然后,设计并向全国高校学生发放问卷,了解全国高校学生图书馆火灾疏散的整体认知水平,确定逃跑空间变化、逃生标志位置熟悉度、情绪传染、逆流行为四个关键因素;最后基于Agent模型、BIM技术、Pathfinder软件与Pyrosim软件对某高校图书馆建模仿真,通过对照实验量化分析四因素对疏散过程的影响.结果表明:四种因素会延长高校图书馆人员疏散时间,并对图书馆安全性能产生不同程度的影响,其中逆流行为影响最大.根据实验结果提出相应改善措施,为我国高校图书馆火灾应急管理提供参考.
College library,with high flammability and population density,is typical enough that a fire broking out in it would set off unanticipated campus chain effects,and it is necessary to analyze the personnel evacuation for college library on fire.Firstly,this study made a comprehensive influence factors summary by literature review.Then,a questionnaire was designed and distributed to some college students nationally to understand the overall cognitive level of college students to fire evacuation in library.And then,this paper concluded the key influence factors which are escape space change,the familiarity of escape sign locations,emotional contagion,and counter flow behavior respectively.Finally,based on Agent model,BIM technology,Pathfinder software and Pyrosim software,a university library was modeled and simulated,and the influence of the four factors on the evacuation process was quantitatively analyzed through comparative experiments.The simulation results showed that all the four factors could extend the evacuation time and affect the security performance of college library in different degree,among which the counter flow behavior was the most prominent factor especially;and based on the experimental data,corresponding improvement measures can be proposed as references for fire emergency management of university libraries in China.
