摘要
为真实地再现人员疏散场景,针对人员疏散过程中的逆流行为问题,提出一种基于社会力模型的人员逆流行为仿真模型,研究在场馆内人员疏散过程中的逆流行为及其对疏散结果的影响。根据社会力模型建立人员疏散模型,采用主从个体之间的吸引力对从个体行动方向的决策作用来描述逆流行为。在有逆流行为情形下的单出口和多出口场馆进行仿真,仿真结果表明,该模型有效且具有可行性,能够模拟出人员疏散过程中的逆流行为,随着逆流个体的增多疏散时间呈非线性增加,在相同情况下主原地等待行为比主不原地等待行为的影响更明显。
To truly reproduce the scene of evacuation,aiming at the problem of counter-current behavior in the process of evacuation,a simulation model of counter-current behavior based on social force model was proposed to study the counter-current behavior in the process of evacuation in multi-exit venue and its impact on the evacuation results.The evacuation model was established according to the social force model,and the decision-making function of the attraction between the master and slave individuals in the direction of individual action was described as the counter-current behavior.The simulation results of single-exit and multi-exit venues with counter-current behavior show that the model is effective and feasible,and it can simulate the counter-current behavior in the process of evacuation.The evacuation time increases nonlinearly with the increase of counter-current individuals.Under the same conditions,the effect of the main individual waiting in place is more obvious than that of the main individual not waiting in place.
