【摘要】 以经典社会力模型为基础,考虑楼梯间行人的各种相互作用力,引入转向概率进行修正,研究人群在楼梯内疏散的运动行为。进一步考虑人流率与时间的关系,提出非匀速下行人运动疏散时间模型,并基于AnyLogic平台模拟仿真,验证了模型的合理性,得到楼梯内行人运动存在的瓶颈现象,并给出相应的措施,为建筑物楼梯的规划与应急疏散引导提供参考。更多还原

【Abstract】 Based on the classic social force model, considering the various interaction forces of the pedestrians in the stairwell, the turning probability was introduced to modify the model and the pedestrian evacuation in stairs was researched. Then, considering the relationship between the pedestrian flow rate and time, an evacuation time model of non-uniform speed descending human movement was proposed. The simulation based on the AnyLogic platform was put forward and it verified the rationality of the model.The potential bottleneck phenomena of pedestrian movement in the stairs was obtained and corresponding measures were put forward to provide reference for planning and guidance of building stairs.更多还原
