摘要
为解决多出口人员密集场所应急疏散的问题,通过对单出口人员疏散过程的分析,揭示了单出口人员疏散的规律,建立了单出口人员疏散计算模型。在此基础上,根据Wardrop第一平衡原理,提出多出口人员密集场所人员疏散的优化模型及适用条件,为制定合理的应急疏散策略及疏散诱导系统提供理论依据。将计算结果与相同条件下社会力模型的仿真结果进行比较,以分析和评价优化模型。
In order to solve the emergency evacuation problem in densely populated place with exits,through the analysis of evacuation process with one exit,evacuation rule of building with one exit was revealed,and calculation model of evacuation under the condition of one exit was established.On this basis,according to the first balance principle of Wardrop,the optimization model of evacuation in densely populated place with exits and application conditions were proposed,providing theory basis for the formulation of reasonable emergency evacuation strategy and evacuation guidance system.At the same time,the results were compared with the simulated results of social force model under the same conditions,Which was used to analyze and evaluate the optimization model.
