教学楼门扇开启角度对人员疏散的影响分析

Analysis of the influence of the opening angle of the door leaf of the teaching building on personnel evacuation

为了探究门扇开启角度对人员疏散的影响,选取门扇的开启角度、安装模式、安装位置、通道宽度和开启状态多个因素作为研究指标,利用Massmotion疏散模拟软件进行人员疏散仿真模拟,探究门扇开启角度与不同因素交互作用下对疏散效率的影响,总结其与疏散时间之间的关系。研究表明:随着门扇开启角度的变化,疏散时间受门扇安装模式的影响较大;随着门扇开启角度、安装位置的相对距离和通道宽度的增大能使疏散时间在一定程度上缩短,其中门扇开启状态也是影响疏散的重要因素。研究结果为建筑的出口结构设计和人员安全疏散管理提供相应参考意见。

In order to explore the influence of the opening angle of the door leaf on personnel evacuation,multiple factors such as the opening angle of door leaf,installation mode,installation position,passage width and opening state were selected as the research object for analysis.The personnel evacuation simulation was carried out in Massmotion evacuation simulation software.The evacuation efficiency under the interaction of door leaf opening angle and different factors was explored,and the relationship between evacuation efficiency and evacuation time was summarized.The results showed that the evacuation time was greatly affected by the installation mode of the door leaf with the change of the opening angle of the door leaf;With the increase of the opening angle of the door leaf,the relative distance of the installation position and the width of the passage,the evacuation time was shortened to a certain extent,and the opening state of the door leaf was also an important factor affecting the evacuation.The research results offer some important insights into the design of the exit structure of the building and the safe evacuation management of personnel.
