摘要
为提高高层建筑紧急状况下的人群疏散效率,降低楼梯拥堵引发的踩踏风险,对比分析了楼梯单向流与双向流疏散模式的差异。通过应用高级仿真软件Massmotion开展具体疏散方式的定量评估,以填补楼梯疏散动态模拟的研究空白。利用软件搭建复杂的疏散模拟模型,在此基础上,设计实验对不同楼梯宽度、不同人数下的单向流和双向流疏散进行了详尽分析。在双向流的实验中,坡度为22.5°~28.0°时,疏散效率更高;当楼梯人数大于60时,采用随意疏散的方式效率更高;在双向流的实验中,双跑对折的疏散时间较长,不宜作为疏通通道,双向流选择排队疏散的方式更为合理。
In order to improve the efficiency of crowd evacuation in high-rise buildings in emergencies and reduce the risk of stampede caused by stair congestion,the difference between single and two-way flow evacuation modes of stairs was compared and analyzed.The quantitative evaluation of specific evacuation modes was carried out by using the advanced simulation software Massmotion to fill the research gap in the dynamic simulation of stairway evacuation.Based on the complex evacuation simulation model built by software,the single and two way flow evacuation under different stairway widths and different number of people were analyzed in detail.The experimental results show that the evacuation efficiency is higher when the slope is from 22.5°to 28.0°.When the number of people on the stairs is greater than 60,the efficiency of random evacuation is higher.The evacuation time of double running and double folding is longer,and it is not suitable to be used as a dredging channel.The way of queue evacuation is more reasonable for two-way flow.
