| 摘 要： | 采用社会力模型对紧急情况下(如火灾发生时)的人员疏散现象进行了模拟，重现了实际疏散中出现的典型现象，着重研究了出口宽度、出口厚度等建筑结构特征以及期望速度等人群特征与疏散时间之间的关系。结果表明，上述建筑结构特征对疏散时间的影响存在一个渐近关系；随着人群期望速度的变化，疏散时间存在一个最佳值。这些结果可望指导建筑物的疏散设计和建筑火灾等紧急情况下人员的安全疏散。

| Abstract: | Pedestrian evacuation during urgency such as fire is simulated through social force model. Some typical phenomena are observed, and the influences of the width and thickness of the exit, as well as the expired speed, on evacuation are studied especially. It is shown that the building structure mentioned above has asymptotic effects on evacuation time and the expired speed has an optimal value under which the pedestrians egress fastest. The results are expected to have practical impact on the evacuation design and safety egress. |
