摘　　要：高地温隧道的封闭性使热量和空气污染物难以及时排出,导致作业环境恶化、工作效率下降,并增加了施工发生故障的风险,通风降温是解决隧道内高地温问题的关键措施.采用Fluent数值模拟软件,以高地温隧道为研究对象建立仿真模型,比较拱顶压入式和侧壁压入式两种通风方式的降温效果.结果表明,拱顶压入式通风在降温效果上优于侧壁压入式通风,其低温风流利用率更高,能够更有效地改善隧道内的高温环境.In high ground-temperature tunnels,due to the closed nature of the tunnel,it is difficult to remove the heat and air pollutants in the tunnel in time,which leads to the deterioration of the operating environment,the reduction of work efficiency and the increase of construction faults.Ventilation and cooling is an important measure to alleviate the problem of high ground temperature in tunnels.In this paper,Fluent numerical simula-tion software is utilized to establish a simulation model with high ground-temperature tunnels as the research object,comparing the cooling effect of the two types of ventilation:vault press-in type and sidewall press in type.The results show that the effect of vault press in ventilation is better than that of sidewall press in ventila-tion.The effective utilization rate of low-temperature airflow is higher,which is more conducive to improving the high-temperature environment in the cave.
