大型体育场馆行人分区疏散优化策略研究*

针对大型场所疏散出口通行能力不均衡现象，以某大型体育场馆为对象，建立Pathfinder疏散模型，通过不断改变行人出口选择，得到行人疏散分区优化模型。结果表明:通过对比优化前后疏散时间、疏散过程及疏散出口利用差异，得到疏散时间优化效率10.55%，各出口疏散时间标准差优化效率为90.78%。分区优化能够均衡各出口疏散时间，提高疏散出口利用效率，有效缓解大型场所拥堵问题，为实现大型场所安全疏散提供理论参考。

Study on optimization strategy and simulation of pedestrian partition evacuation in large stadiums

The use of evacuation exits in large stadiums cannot match the corresponding number of seats.During an emergency evacuation,the evacuation exits will be idle after the evacuation is completed,and some exits will remain congested,reducing the overall evacuation efficiency.Aiming at the phenomenon that the passage capacity of each evacuation exit cannot be fully utilized,an optimization strategy of pedestrian partition evacuation was proposed.Taking a large stadium as an example object,a Pathfinder evacuation model was established,and multiple simulation iterations were conducted on the basis of the initial model without pedestrian partition,and the choice of pedestrian exits was changed constantly to obtain the optimized pedestrian evacuation partition map.Finally,by comparing and analyzing the evacuation time,evacuation process and difference in utilization of each exit before and after optimization,the optimization efficiency of evacuation time was 10.55%,and the optimization efficiency of standard deviation for the evacuation time of each exit was 90.78%.The research results showed that the optimized evacuation strategy of pedestrian partition can shorten the evacuation time of stadiums and balance the utilization rate of each exit.
