摘　　要：隧道通风一直是制约隧道施工的难题,通风的好坏直接影响施工效率、作业环境及作业人员身体健康,尤其是高原隧道,在海拔高、低气压、低含氧量等因素影响下,存在高原缺氧、内燃机械降较大、作业人员效率低下等困难,如何有效解决问题,高效的通风是有效的措施之一。结合某高原长大隧道的巷道式通风方案,从通风计算、风机选型与配置、风速监测与测点布设等方面进行论述,给出了适用的通风方案设计结果,满足了长大隧道通风施工的技术需求,可为同类工程施工提供参考。Tunnel ventilation has always been a difficult problem that restricts tunnel construction.The quality of ventilation directly affects construction efficiency,working environment,and the physical health of workers,especially in high-altitude tunnels.Under the influence of factors such as high altitude,low air pressure,and low oxygen content,there are difficulties such as high-altitude hypoxia,large efficiency reduction of internal combustion engines,and low efficiency of workers.Efficient ventilation is one of the effective measures to effectively solve these problems.This article discusses the gallery ventilation scheme of a certain plateau long tunnel and expounds from the aspects of ventilation calculation,fan selection and configuration,wind speed monitoring and measurement point layout,etc.It provides applicable ventilation scheme design results,which meet the technical requirements of ventilation construction for long tunnels and can provide reference for similar engineering construction.
