| 摘 要： | 为准确快速估算室内人员疏散时间，基于传统Togawa模型，提出1种基于出口处人员流动速率的室内人员疏散时间快速预测模型，并利用Pathfinder软件模拟某房间人员疏散过程，对比快速预测模型与传统Togawa经验公式计算结果。结果表明:快速预测模型计算量少，可获得更多更精确人员疏散信息。研究结果可为室内人员疏散提供理论支撑。

| Abstract: | In order to accurately and quickly estimate the indoor personnel evacuation time,based on the traditional Togawa model,a rapid prediction model of indoor personnel evacuation time based on the personnel flow rate at the exit was proposed.Compared with the traditional Togawa model,the rapid prediction model did not require the global calculation,and the calculation efficiency was higher.The Pathfinder software was used to simulate the personnel evacuation process of a room,and taking the simulation results as reference,the calculation results of the rapid prediction model and the traditional Togawa empirical formula were compared.The results showed that the rapid prediction model had less calculation amount and could obtain more and more accurate personnel evacuation information.The research results can provide theoretical support for the indoor personnel evacuation. |
