商业建筑群天桥辅助人员疏散探讨

The studies on the overpass layers aiding the evacuation of the staff in commercial buildings

以临沂名嘉城市广场为背景,研究了大型商业建筑群利用天桥辅助人员疏散的可行方案。利用人员疏散计算机模拟软件Pathfinder模拟计算了不同天桥设置情况下建筑群中人员疏散的行动时间。通过对背景工程建立计算模型,对不同天桥设置情况下的疏散进行模拟,并对计算得出疏散时间进行分析对比,得出天桥设置层数的最佳设置方案。

The Mingjia Plaza of Linyi City was set as the background and the feasible schemes of evacuating the staff with the assistance of the overpass in large-scale commercial buildings was studied.The computer simulation software Pathfinder 2009 was adopted to simulate and calculate the action time of the evacuation under different overpass settings.The optimal scheme was drawn by setting computing models for the engineering background,simulating the situations of evacuation under different overpass settings and comparatively analyzing the different time those evacuations took.
