【摘要】:为研究公共场所内引导员的设置对紧急疏散及逃生效率的影响,进行了3种工况的紧急疏散仿真模拟研究。基于分区疏散理念进行疏散区域的划分和引导员位置的设置,运用Building Exodus软件对3种工况下的人员紧急疏散情况进行仿真模拟,3种工况为无引导员、基于最短路径原则而设置引导员、综合考虑出口通行能力和最短路径原则而设置引导员。计算3种工况下的待疏散人员逃生效率及逃生时间,并进行对比分析。结果表明:综合考虑出口通行能力和最短路径原则设置引导员的工况,其出口利用率及逃生效率均最高,逃生效率的最佳工效统计(OPS)为0.087;基于最短路径原则设置引导员的工况位居其次,由于没有合理利用出口,导致所使用的逃生时间和无引导员工况的逃生时间相近,最佳工效统计(OPS)为0.417;无引导员工况的最佳工效统计(OPS)为0.443。仿真模拟研究结果表明,在公共场所紧急疏散时,按综合考虑出口通行能力和最短路径原则设置引导员,可提高人员疏散效率和出口利用率,同时减少人员疏散时间。
[Abstract]:In order to study the influence of guidance staff in public places on emergency evacuation and escape efficiency, the simulation of emergency evacuation under three conditions was carried out. Based on the concept of regional evacuation, the evacuation area is divided and the location of the guide is set. The emergency evacuation is simulated under three conditions by using Building Exodus software. Based on the principle of the shortest path, the guide is set up, considering the capacity of the exit and the principle of the shortest path. The escape efficiency and escape time of the evacuees were calculated and compared with each other. The results show that the optimal working efficiency of exit utilization rate and escape efficiency is the highest, and the optimal (OPS) of escape efficiency is 0.087; Based on the principle of the shortest path, the working condition of setting the guide is next, because there is no reasonable use of the exit, the escape time used is similar to that of the workers without guidance. The best work efficiency statistic (OPS) is 0.417; The (OPS) of the best work efficiency statistics for unguided employees was 0.443. The simulation results show that in the emergency evacuation of public places, the efficiency and efficiency of evacuation can be improved and the evacuation time can be reduced by setting the guide according to the principle of comprehensive consideration of exit capacity and shortest path.
