【摘要】：从行人疏散过程和紧急疏散出口通过能力的角度,分析行人步行设施紧急疏散出口设置的影响因素,并提出紧急疏散出口设置方法.研究发现,在总宽度一定的情况下,紧急疏散出口的个数越多,其相应的总通过能力越低.基于步行设施内疏散行人的数量、初始位置,紧急疏散出口的行人通过能力,多紧急疏散出口的行人选择策略,以及紧急疏散出口的设置指标,构建了行人步行设施紧急疏散出口设置的优化模型;并提出其简化的求解算法,实现紧急疏散出口个数、位置和宽度的优化设置.结合算例,从紧急疏散出口布局优化的角度,提出北京市西直门换乘枢纽紧急疏散出口布局的改进措施.
[Abstract]:From the point of view of pedestrian evacuation process and emergency evacuation exit capacity, this paper analyzes the influencing factors of emergency evacuation exit setting of pedestrian walking facilities, and puts forward the method of emergency evacuation exit setting. It is found that the more the number of emergency evacuation exits is, the lower the corresponding total capacity is when the total width is certain. Based on the number of evacuating pedestrians in pedestrian facilities, the initial position, the pedestrian passing capacity of emergency evacuation exits, the pedestrian selection strategy of multiple emergency evacuation exits, and the setting index of emergency evacuation exits, the optimization model of emergency evacuation exit settings of pedestrian walking facilities is constructed, and a simplified algorithm is proposed to realize the optimal setting of the number, position and width of emergency evacuation exits. Combined with an example, from the point of view of optimization of emergency evacuation exit layout, the improvement measures of emergency evacuation exit layout of Xizhimen transfer hub in Beijing are put forward.
