归纳和分析影响应急安全疏散效率的相关因素.以合肥城市学院南教学楼为研究背景.应用Pathfinder 进行模拟.在控制变量的情况下.分别针对上课和下课时段.研究不同的疏散路线对疏散效率以及疏散耗费时间的影响.同时在控制变量的情况下.分析疏安全出口数量对疏散效率以及疏散耗时的影响.多层建筑物出口数量的多少影响疏散时间.双跑楼梯比单跑楼梯的疏散效率更高.但更容易发生拥堵.要合理安排疏散路线.

The related factors affecting the emergency evacuation efficiency were summarized and analyzed. Taking the South Teaching Building of Hefei City University as the research background. the Pathfinder was applied to simulate. In the case of control variables. the effects of different evacuation routes in class and after class on evacuation efficiency and evacuation time were studied respectively.At the same time. the influence of the number of exits on evacuation efficiency and evacuation time was analyzed. The evacuation time was affected by the number of exits multi-storey buildings.The evacuation efficiency of double-run stairs was higher than that of single-run stairs. but congestion was more likely to occur. Evacuation routes should be arranged reasonably.
