  随着我国在高海拔或寒冷地区修建的隧道日益增多,这些地区常因其特殊的气候环境,加之地下水比较发育,隧道常常会发生冻害,直接威胁到隧道结构及运营行车的安全,造成严重的经济损失。因此,对寒区隧道温度场性状的监测研究是目前寒冷地区隧道工程中亟待解决的一个重大课题。本文以甘肃寒区公路隧道高岭公路隧道建设为契机,以服务工程为目的,开展了较大规模的现场测试工作,对隧道温度场进行了监测并提出了温度场监测的数据分析方法。

AbstractWith the tunnel construction increasing in the special climate and environment of high altitude and cold areaand the underground water developmentthe tunnels often produce frost damages which lead direct threat to the tunnels safety and transport service. So it’s a major issue to be solved at present in cold area tunnel engineering to study on tunnels temperature fields characters monitoring. In this papertaking the Gaoling highway tunnel construction in the cold region of inner Gansu as an opportunityand serving for the projectthe tunnel temperature fields were monitored and data analysis method is presented.
