【摘要】：從行人疏散過程和緊急疏散出口通過能力的角度,分析行人步行設施緊急疏散出口設置的影響因素,并提出緊急疏散出口設置方法.研究發(fā)現,在總寬度一定的情況下,緊急疏散出口的個數越多,其相應的總通過能力越低.基于步行設施內疏散行人的數量、初始位置,緊急疏散出口的行人通過能力,多緊急疏散出口的行人選擇策略,以及緊急疏散出口的設置指標,構建了行人步行設施緊急疏散出口設置的優(yōu)化模型;并提出其簡化的求解算法,實現緊急疏散出口個數、位置和寬度的優(yōu)化設置.結合算例,從緊急疏散出口布局優(yōu)化的角度,提出北京市西直門換乘樞紐緊急疏散出口布局的改進措施.
[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.
