大型场馆疏散模拟优化策略分析

Analysis on Optimization Strategy of Evacuation Simulation for Large Venues

针对大型场所疏散出口通行能力不均衡现象,以某大型场馆为对象,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,得到疏散时间优化效率15%,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。

Aiming at the imbalanced phenomenon of evacuation exit capacity in large venues, taking a large venue as the object, the Pathfinder evacuation model is established, the optimization model of pedestrian evacuation zone is obtained by changing the choice of pedestrian exit constantly. The results show that by comparing the evacuation time and evacuation process before and after optimization, the optimization efficiency of evacuation time is 15%, which effectively alleviates the congestion problem in large venues, so as to provide theoretical reference for the realization of safe evacuation in large venues.
