摘　　要：为探究海峡特长铁路隧道疏散设施对人员疏散时间的影响,利用Pathfinder人员疏散模拟软件分别以横通道宽度、横通道间距、疏散通道宽度和疏散人数为变量,对不同变量影响下人员疏散时间的变化趋势进行分析。结果表明,横通道宽度对人员疏散时间的影响以2 m为分界,呈现阶段性差异的特征;人员疏散时间与横通道间距线性相关;疏散通道宽度和疏散人员荷载与疏散用时的关系分别为幂指数关系和二次函数增长关系。建议特长铁路隧道疏散系统设计时,应兼顾工程施工建设和后期运营管理,并有针对性地开展疏散系统参数评估。In order to explore the influence of evacuation facilities on the evacuation time in strait super long railway tunnel,evacuation models are established by Pathfinder.It takes the cross passage width,cross passage spacing,evacuation passage width and the number of persons evacuated as the main variables,mainly analyzes the changing trend of evacuation time under different variables.The results show that,the cross passage width with 2m as the boundary has a stepwise effect on the evacuation time.The evacuation time is linearly related to the change in cross passage spacing.The relationship between the evacuation passage width and the occupant load with the evacuation time show exponential relationship and growth relation of quadratic function respectively.When designing an evacuation system for a super long railway tunnel,it is suggested to take into account the construction feasibility and the subsequent operation management,and carry out a targeted evaluation for the evacuation system.
