基于行人仿真技术的地铁车站疏散能力模拟测试方法分析

Simulation Test Method of Subway Station Evacuation Capacity by Pedestrian Simulation

城市轨道交通车站疏散能力是车站设计过程中的重点之一,车站设施能力设计要满足紧急情况下的乘客疏散要求。交通运输部要求地铁线路初期运营前应编制大客流车站的通过能力模拟测试报告,但对于具体技术方法和编制深度等并没有统一要求。基于行人仿真技术并结合天津地铁8号线一期工程,提出了地铁车站疏散能力模拟测试工作要点,评价了实例中疏散时间指标和人流密度指标,分析了疏散方案优化前、后情况,为类似工程提供了参考。

Evacuation capacity of urban rail transit station is one of the key points in the station design process.The design capacity of station facilities and equipment shall meet the requirements of passenger evacuation in emergency.The Ministry of Transport requires that the simulation test report of the passing capacity of large passenger flow stations should be prepared before the initial operation of the subway line.There is no uniform requirement for the specific technical method and preparation depth.Based on pedestrian simulation technology,combined with the actual project of Tianjin Metro Line 8,the key points of the evacuation capacity of the station was put forward in this paper.The evacuation time indicators and crowd density indicators were evaluated in this case.The evacuation scheme was analyzed before and after optimization.It can provide references for similar projects.
