摘要
高海拔隧道运营通风设计对于节省运营期通风费用以及保证行车安全意义重大。本文从正常运营通风设计、通风节能设计及防灾救援技术等方面总结归纳了高海拔公路隧道运营通风的最新研究成果,主要包括需风量设计中考虑CO及烟雾影响的海拔高度系数、自然风及交通风节能技术、高海拔对风机选型影响规律、高海拔公路隧道防灾救援技术中的火灾燃烧规律及人员逃生速度研究。研究成果对川藏公路运营通风设计具有一定的指导意义。
The operational ventilation design in high-altitude tunnels is of great significance for saving costs during operation period and ensuring driving safety.This paper summarized the state-of-the-art operational ventilation researches on the aspects of standard operational ventilation design,energy-efficiency ventilation design as well as disaster prevention and rescue technology in high-altitude highway tunnels.It mainly includes altitude coefficient considering CO and smoke in the design of air volume,natural wind and traffic wind energy-efficiency technology,influence of high altitude on fan selection,combustion behavior of fire and personnel evacuation speed in disaster prevention and rescue technology.This research can provide references for the operational ventilation design in Sichuan-Tibet Highway.
