在铁路隧道工程建设中,隧道运营通风的设计将直接影响隧道的运营环境、救灾功能以及运营效益等。隧道通风设计是整个铁路运输系统需要解决好的关键。本文主要从铁路隧道通风方式的选择、铁路隧道污浊空气的稀释标准以及竖井送排式通风的通风问题三个方面对特长铁路隧道通风设计的相关问题进行阐述。 In the construction of railway tunnels, the design of tunnel ventilation will directly affect the operation environment, disaster relief functions and operational benefits of the tunnels. Tunnel ventilation design is the key to solve the entire railway transport system. This article mainly elaborates the related issues of ventilation design of the special railway tunnel from the aspects of the choice of ventilation mode of railway tunnel, the dilution standard of the polluted air of railway tunnel and the ventilation of the shaft ventilation ventilation.
