摘要: 某大型中央商务区地下空间通过11个连通道将7个独立区域连通。设置11个场景,利用Pathfinder进行定量化计算分析,分析将可用连通道视作室内相对安全出口对人员疏散效率的影响。分析典型区域增加连通口后的疏散时间以及各连通口的疏散人流量。结果表明,连通道附近人员充分利用其进行疏散,路径的增加使人员疏散得到优化,有利于提升人员疏散效率。

Abstract: The underground space of a large CBD connects 7 independent areas through 11 connecting channels. Pathfinder was used to analyze the effect of considering the available passageway as the indoor relative safety emergency exit on the evacuation efficiency quantitatively by 11 scenarios. The evacuation time after increasing the connecting ports and the evacuation flow of each connecting port in typical areas were analyzed. The results showed that people near the company channel can make full use of it for evacuation, and the increase of the path can optimize the evacuation, its conducive to improving evacuation efficiency.

Key words: underground space, connecting project, numerical simulation, evacuation efficiency
