摘要
区间疏散是地铁设计需要重点考虑的防灾设计问题。为了研究有效的地铁区间疏散方式,利用基于个体的人员疏散计算模拟方法,对不同的区间疏散方式下的疏散能力、疏散时间和疏散瓶颈位置进行了计算模拟研究。研究表明端门疏散方式的瓶颈在客车司机与客室之间的门和车辆端头门的下行梯位置,而侧向平台疏散方式的瓶颈在于疏散平台的宽度;侧向疏散平台方式可以让疏散乘客"较为有序",整体疏散时间比端门疏散有了较大的缩短。当疏散平台宽度增加至800mm时,疏散时可以形成两股疏散人流,进一步提高疏散效率。分析结果可为工程设计人员、安全评估人员提供参考。
Tunnel evacuation is an important aspect to be focused on in the design of disaster prevention for the metro design.In order to study the effective evacuation mode in the metro tunnel,through the agent-based evacuation simulation method,the evacuation capacity,evacuation time and bottleneck location for different tunnel evacuation mode were investigated by simulation.The results showed that the lateral evacuation platform can be used as a relatively effective evacuation mode to evacuate passengers to the outside of the train orderly.The bottleneck for the end door evacuation mode is the descending ladder in the end door and the passage between the driver cab and passenger carriage,but for the lateral evacuation platform mode,it is the width of the lateral evacuation platform.The lateral evacuation platform can provide ＂a more orderly evacuation from the train,＂ and the overall evacuation time away from the train is greatly reduced.If the width of evacuation platform increases to 800mm,the evacuation efficiency can be further improved by the forming of two flows of passengers.The result can provide a reference for the personnel of engineering design and safety evaluation.
