摘要: 以高校大学生为研究对象,通过开展人员负重行走实验,研究典型行李负重对步行疏散速度的影响。在出行负重情况问卷调研的基础上进行人员负重行走实验,结果表明,最大负重工况中,与无负重相比,携带双肩背包、手提包和斜挎包行人的平均疏散速度分别下降6.0%、3.6%和4.2%。拟合结果表明,随着行李质量增大,携带双肩背包和斜挎包行人的平均疏散速度基本呈线性下降;携带手提包行人的平均疏散速度下降则符合指数规律。随行李箱质量不同,人员行走速度下降程度也不同。

Abstract: Taking college students as the examinee, based on the questionnaire survey results, the influence of baggageweight on the evacuation speed of pedestrians was investigated through experiments on people walking with baggage. The results show that: Under the heaviest weight of the backpack, handbag, messenger bag, the average evacuation speed of pedestrians decreases 6.0% , 3.6% and 4.2% compared with the no baggage condition. Based upon data fitting, the average evacuation speed of the pedestrians with backpack and messenger bag decreases linearly with the baggage weight, while the average evacuation speed of pedestrian with handbag decreases with the baggage weight exponentially. As the luggage case weight changes, the decrease trends of evacuation speed are different.
Key words: baggage weight, safety evacuation, evacuation speed, experimental study
