摘要:
为了模拟毒气泄漏情景下的人群疏散过程，提出了考虑人群拥堵和毒气危害的出口选择模型，在地面场疏散模型的基础上扩展了毒气场表达和毒气信息传递模式。将出口选择模型引入扩展的疏散模型进行人群疏散仿真，分析了出口间隔、毒气场参数、毒气源位置对不同出口疏散时间和人数的影响。研究结果表明：出口间距的设置存在临界值，设置大小应避免等于该临界值，否则容易造成行人频繁变换目标出口，且人的视野半径越大，该取值越大；毒气源位置对疏散结果具有显著影响，毒气的扩散范围影响较小，但由于影响到毒气信息携带者的数量，毒气扩散范围会导致疏散结果的不确定性。
Abstract:
In order to simulate the crowd evacuation process in the scenario of toxic gas leakage, an exit selection model considering the crowd congestion and toxic gas hazards was proposed, and the ground field evacuation model was extended with the expression of toxic gas field and the mode of toxic gas information transfer. The crowd evacuation simulation was carried out by introducing the exit selection model into the extended evacuation model, and the influence of exit separation, parameters of toxic gas field and location of toxic gas source on the evacuation time and number of people of different exits was analyzed. The results showed that the setting of exit separation had a critical value, while the setting value of exit separation should avoid being equal to the critical value, otherwise it would be easy to cause that the pedestrian change their targeted exit frequently, and the larger the visual radius of the person, the larger the critical value. The location of toxic gas source had a significant effect on the evacuation results, while the diffusion range of toxic gas had less effect. But due to the influence on the amount of toxic gas information carriers, the diffusion range of toxic gas would cause the uncertainty of evacuation results.
