摘要
随着全球气候变暖,沿海沿江城市频繁出现强降水等极端天气,地铁车站水侵事故时有发生.为制定合理的地铁水侵应急疏散策略,提高乘客应急疏散效率,基于AnyLogic平台构建车站水侵疏散仿真模型,并以中国深圳市车公庙地铁站为例,研究水侵条件下应急疏散策略对疏散效率的影响.仿真结果表明,进水点数量与位置对疏散结果有较大影响;车站水侵级别在一定程度上影响疏散效率;综合考虑将自动扶梯用作楼梯使用、布设导流栏及增设应急疏散口3种疏散策略,优化后模型的疏散效率整体提高了11.4%,安全疏散比例达到92.2%.仿真结果可为地铁车站预防水侵的疏散设计与运营管理提供参考.
With the global warming, extreme weather such as heavy precipitation frequently occurs in coastal and riverside cities, which may cause water invasion accidents in subway stations due to heavy rainstorm. In order to formulate a reasonable strategy for emergency evacuation of water invasion in subway stations and improve the efficiency of emergency evacuation of passengers, we build a simulation model of station water invasion evacuation based on AnyLogic simulation platform. We take Shenzhen Metro Chegongmiao Station as an example to study the impact of emergency evacuation strategy on the evacuation efficiency under water invasion conditions. The simulation results show that the number and location of the inlet points have a great influence on the evacuation result. The level of water invasion affects evacuation efficiency to a certain extent. Considering three evacuation strategies of using escalators as stairs, laying diversion fences and adding emergency evacuation exits, the evacuation efficiency of the optimized model is improved by 11.4%, and the safe evacuation ratio reaches 92.2%. The simulation results can provide reference for evacuation design and operation management of subway station under water invasion.
