基于纵向通风的铁路隧道救援站横通道设置研究

摘要

救援站结构形式多种多样，目前并没有统一的设计标准。但救援站结构形式决定了人员疏散效率，同时又影响着通风方案的设计。结合现有人员疏散模型与相关规范从救援站结构形式对人员疏散效率及烟气流动的影响的角度进行研究，为救援站结构设计提供依据。对于救援站采用纵向通风时，横通道风速的一种产生形式进行了模拟分析。%Rescue station structure forms, there is no uniform design standards. But the rescue station structure determines the evacuation efficiency, but also affects the design of the ventilation scheme. In this paper, combined with the existing evacuation model and relevant rules for rescue station structure influence the efficiency of flue gas flow and evacuation of personnel to carry out research, provide the basis for the rescue station structure design. For rescue station using longitudinal ventilation, a form of cross passage wind speed is simulated and analyzed.
