摘要
为提升电影院人员安全疏散效率,利用Pathfinder人员疏散模型,研究观众厅不同疏散出口数量、出口宽度、过道宽度和出口布局对疏散效率的影响。结果表明,出口个数、过道宽度和出口布局对疏散效率影响显著。出口个数越多,疏散效率越高;过道宽度是影响疏散效率的关键参数,消除疏散拥堵瓶颈应从提升过道宽度考虑;出口布置在影厅下部对疏散更有利。出口宽度在1.4~1.8 m变化时对疏散效率影响差别不大。
To improve the evacuation efficiency of the audience hall, evacuation model was established by Pathfinder to study the effects of exit number, exit width, aisle width and exit positions on the evacuation efficiency. The results showed that exit number, aisle width and exit positions have significant effects on the evacua- tion efficiency. It is useful to set up more exits to improve the evac uation efficiency and lhe evacuation bottle necks can be obviously eliminated by increasing the aisle width. It is useful for the evacuation by setting the exits on the fronl of the audience hall. The change of lhe exit width from 1.4 m to 1.8 m has little impact on the evacuation efficiency.
