Influence of urban underground space connection project on evacuation

Abstract

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
