摘　　要：人群运动过程中人与人、人与建筑之间的相互作用非常复杂,涉及到人的心理和行为特征、人群特征和环境特征等多种因素。以现有的社会力模型为基础,考虑到行人运动的各向异性、行人对于动态阻塞区域的避让行为,提出了一种改进模型。该模型能更为真实的体现人群的实际运动,模拟人群运动的分层自组织现象。将改进后的模型应用于人群拥挤的行为特性研究,其结论可为公共场合的建筑通道设计提供一些依据。When pedestrians move, the interaction between people and building is very complex, involving many factors, such as pedestrian＇s psychological and behavioral characteristics, environmental features and so on. Based on the existing social force model, an improved model was put forward which took into account the anisotropic characteristic of pedestrian movement, the avoidance of dynamic congested areas. The model will be better in describing the actual movement of crowd, such as self-organization phenomena in pedestrian crowds. The improved model was applied for research on pedestrian crowding characters and its conclusions can nrovide some basis for the design of public passages.
