| 摘 要： | 为确定铁路隧道救援站最佳通风结构，对烟道布置提出合理建议，采用计算流体力学（CFD）的方法，对铁路隧道救援站通风网络进行优化设计。同时，采用模拟计算的方法对救援站人员疏散进行模拟分析，确定救援横通道布置及防护门开度设置的合理性。研究结果表明:在同等通风参数工况设置下，采用多节点排烟竖井结构后各救援横通道流量分配更均匀，救援站压力平衡性更好，通风效率可提升15%；通过疏散模拟证实，在长560 m的紧急救援站范围内设置10条疏散横通道，横通道设1.7 m宽的逃生门能够满足疏散要求。

| Abstract: | In order to determine the optimal ventilation structure of the railway tunnel rescue station,the reasonable suggestions for the layout of flue were put forward,and the computational fluid dynamics (CFD) method was used to optimize the design of ventilation network in the railway tunnel rescue station.At the same time,the method of simulation calculation was used to simulate and analyze the personnel evacuation of the rescue station,so as to determine the rationality of the arrangement of the rescue cross passage and the opening setting of the protective door.The results showed that under the setting of the same ventilation parameters,the multi node smoke exhaust shaft structure was adopted,and the flow velocity distribution of each rescue cross passage was more uniform,then the pressure balance of the rescue station was better,and the ventilation efficiency could be increased by 15%.It was validated by the evacuation simulation that the evacuation requirements could be satisfied when setting 10 evacuation cross passages within the range of emergency rescue station with a length of 560 m and laying an escape door with a width of 1.7 m in the cross passage. |
