【摘要】：为解决群体疏散连续模型中的多出口选择问题,通过考虑可视范围对行人之间心理作用力的影响,修正社会力模型.引入出口效用函数,从出口客观条件(设计因素和距离因素)以及堵塞效应对行人心理的影响出发,建立基于出口效用评估的多出口选择模型.并将其与修正后的社会力模型结合,构建多出口选择群体疏散综合模型.最后利用Microsoft Visual Studio编程软件,实现多出口建筑物内大规模群体运动的有效模拟,验证多出口选择的群体疏散模型的有效性.
[Abstract]:In order to solve the problem of multi-exit selection in the continuous model of mass evacuation, the social force model was modified by considering the influence of visual range on the psychological force between pedestrians. Based on the objective conditions (design factors and distance factors) and the influence of blockage effect on pedestrian psychology, a multi-exit selection model based on the evaluation of export utility is established by introducing the exit utility function. Combined with the modified social force model, the multi-exit selection group evacuation comprehensive model is constructed. Finally, the simulation of mass movement in multi-exit buildings is realized by using Microsoft Visual Studio programming software, and the validity of the multi-exit evacuation model is verified.
