摘　　要：学校属于人员密集度较高的公共场所。以教学楼为研究对象,实际调查其布局与人员流动情况,建立了相应的火灾疏散模型,考虑最不利原则的基础上结合两种经验公式及Pathfinder模拟,计算了其必需疏散时间。计算所得结果为探测报警时间为20 s,人员反应时间为40 s,计算得出最不利条件下教室滞留时间为161.61 s,教室门口疏散时间为57.34 s,楼道疏散时间为101.95 s,必需疏散时间为380.9 s。最后对必需疏散时间的占比进行了分析,得出了减少疏散时间的建议。Schools belong to public places with high personnel density.This article takes the teaching building as the research object,actually investigates its layout and personnel flow,establishes a corresponding fire evacuation model,and combines two empirical formulas and Pathfinder simulation to calculate its necessary evacuation time on the basis of considering the most unfavorable principle.The result shows that detection alarm time is 20 seconds,personnel response time is 40 seconds,and that under the most unfavorable conditions,retention time in the classroom is 161.61 seconds,evacuation time at the classroom entrance is 57.34 seconds,evacuation time in the hallway is 101.95 seconds,and necessary evacuation time is 380.9 seconds.Finally,this paper analyzes the proportion of necessary evacuation time,and obtains recommendations to reduce evacuation time.
