【摘要】：为研究突发事件下行李类别对人员疏散的影响,改进社会力模型中的驱动力变量,提出紧张系数、出口可靠性等参数的定量计算方法。以成都某大型汽车站为例,针对行李种类及其比率、总疏散人数,运用仿真软件Anylogic进行模拟,对比分析原模型仿真结果,提出应急改善建议。结果表明,负重者会根据自身条件及目标出口情况调整路径;就给定总人数和行李类别而言,随负重者比率提高,疏散时间增加,且疏散携带拉杆箱的人员所需时间最长;总人数与疏散时间正相关。
[Abstract]:In order to study the influence of baggage category on evacuation under sudden events and improve the driving force variables in social force model, a quantitative calculation method of tension coefficient, exit reliability and other parameters is put forward. A large bus station in Chengdu is taken as an example. According to the type of baggage and its ratio, the total evacuation number, the simulation software Anylogic is used to simulate and analyze the simulation results of the original model, and some suggestions for emergency improvement are put forward. The results show that the load-bearing person will adjust the path according to his own condition and the target exit condition. For a given total number and baggage category, the evacuation time increases with the increase of the weight bearing ratio, and the longest evacuation time is required for the person carrying the pull-box, and the total number is positively related to the evacuation time.
