【摘要】 从人员在建筑物紧急疏散时同前后及左右人员拥挤对人员启动加速度的影响机理出发 ,建立了人员疏散动力学方程 ,并推导出人员在拥挤环境下的移动速度公式 ,得到人员移动速度与人员拥挤密度呈对数的关系 ,与前人观测数据基本吻合 .通过拟合分析表明前后人员的影响远大于侧向 .更多还原

【Abstract】 The dynamical equation of evacuation speed for personnel has been found from the principle that the acceleration is subjected to the crowd degree both the back_front and the two_side. The speed equation has also been derived when people egress from buildings. The relationship between the crowd density and the speed presented logarithmically. It is good agree with the experimental data. The study also presents that the influence of the two_side is inferior to the front and back.更多还原
