教学楼发生突发事件可能会给人员及财产造成巨大损失,合理有效的疏散方案对减少人员伤亡具有重要的意义。本文使用当前国外先进的应急疏散模拟软件Pathfinder,在构建教学楼模型和数据收集基础上,对原有方案下的疏散、学生疏散路径进行规划后的疏散和调整各年级教室位置后的疏散进行了仿真。我们发现当所有出口的利用率近乎相同的时候整个教学楼的疏散时间是最短的,以此我们总结出制定疏散预案需要遵循的规律。同时我们发现只要在人员固定的情况下,各年级教室的位置不管怎么变化,对疏散总时间不会造成影响。在制定疏散方案的时候,应该遵循所有出口利用率一致的规律,合理规划学生的疏散路径,提高疏散效率。
Emergencies in the teaching building may cause huge losses to personnel and property. A reasonable and effective evacuation plan is of great significance to reducing casualties. In this paper, the current foreign advanced emergency evacuation simulation software Pathfinder, build teaching building model and data collection based on the evacuation of the original program evacuation, the evacuation of students after the evacuation path planning and evacuation of classroom placement after the grade simulation. We find that the evacuation time of the entire school building is the shortest when the utilization rates of all outlets are almost the same, and we conclude the rules to be followed in formulating the evacuation plan. At the same time, we found that as long as the staff fixed, the position of classrooms of all grades no matter how the change, the total time of evacuation will not be affected. In formulating the evacuation plan, all laws governing the consistent export utilization should be followed to rationally plan the evacuation routes for students and improve evacuation efficiency.
