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。
In order to study the influence of baggage category on personnel evacuation under emergencies and improve the driving force variables in social force model, a quantitative calculation method of tension coefficient, export reliability and other parameters is proposed. Taking a large bus station in Chengdu as an example, anylogic simulation software was used to simulate the baggage types, their ratios and total evacuation numbers. The simulation results of the original model were compared and the suggestions for emergency improvement were put forward. The results showed that the load-bearing persons would adjust the route based on their own conditions and the target exit situation. For a given total number of persons and baggage categories, the time required for evacuation of carrying passengers was the longest as the proportion of load-bearing persons increased and evacuation time increased. The total number and the evacuation time are positively correlated.
