疏散拥堵是火灾中导致人员伤亡的重要因素,因此合理有效地解决疏散过程中的拥堵问题对于提高疏散效率,减少人员伤亡具有现实意义。针对此问题引入延迟疏散法,运用buildingEXODUS软件进行模拟研究,重点讨论不同反应时间间隔对疏散时间的影响。通过某高校宿舍楼的模拟研究发现,反应时间间隔为5s时,人群的疏散时间最短,疏散效率最高。当无反应时间间隔时,疏散时间增长20s;随着反应时间间隔增长,疏散时间也不断增长。该结果对疏散预案的制定和优化有一定的借鉴意义。
Evacuation congestion is an important factor leading to casualties in the fire. Therefore, it is of practical significance to solve the congestion problem in the evacuation process reasonably and effectively to improve evacuation efficiency and reduce casualties. A delay evacuation method was introduced to solve this problem. BuildingEXODUS software was used to simulate the impact of different response time intervals on evacuation time. Through a university dormitory simulation study found that the response time interval of 5s, the crowd evacuation time is the shortest, the evacuation efficiency of the highest. When no reaction time interval, the evacuation time increased 20s; as the reaction time interval increases, the evacuation time also continues to grow. The results of the evacuation plan formulation and optimization of a certain reference.
