| 摘 要： | 在建立走廊转角疏散模型的基础上，将房间人员密度设置4种情况，采用计算机数值模拟软件FDS＋Evac模拟了不同转角角度，不同圆角半径的走廊转角条件下的人员疏散过程。研究表明：走廊转角角度从O°增加到90°，疏散时间先增长然后缩短最后又增长。同条件下，圆角疏散能力优于折角。圆角半径大小对人员疏散没有显著影响。研究结果为建筑走廊设计提供了参考依据。

| Abstract: | Pedestrian evacuation during different corridor comer conditions is simulated by using FDS ＋ Evac. The evacuating model and four kinds of occupant density of the room are set up. In the same time, evacuation is simulated by the model in different angle and fillet radius of corridor comer. The analytical results show that evacuation time increases at first, then getting down, and getting up again finally, as the angle increasing from 0°to 90°. Under the same conditions, evacuation ability in round-side comers is better than that in break angle. Size of round-side radius has no significant affections on evacuation. Results of the research provide reference for building design of corridor. |
