基于实测数据的地下通道行人疏散运动规律

Movement Regularity of Pedestrian Evacuation in Underground Passages Based on Measured Data

为揭示地下通道内人群运动规律,保障地下空间人群安全,选取某地下通道开展人群运动观测实验,采集获取了824个行人样本数据,统计了人群速度、步频分布情况及密度-流量关系,并分析了性别、年龄、是否携带物品与结伴下的疏散运动参数差异。结果表明:性别、年龄与个体的速度、步频显著相关性,速度与步频之间呈现显著相关性,个体速度由其步频决定。研究结果可为地下空间疏散设计提供参考,有助于提升地下通道及地下空间人群安全管理水平。

In order to reveal the law of crowd movement in underground passages and ensure the safety of crowd movement in underground spaces,an underground passage was selected to carry out a crowd movement observation experiment,and 824 pedestrian sample data were collected.The crowd speed,step frequency distribution and density-flow relationship were counted,and the differences of evacuation motion parameters among gender,age,carrying goods and accompanying are analyzed.The results show that gender and age are significantly correlated with individual speed and stride frequency,and there is a significant correlation between speed and stride frequency,and individual speed is determined by their stride frequency.The research results can provide references for underground space evacuation design and help improve the safety management of underground passages and underground space crowds.
