Monitoring of Longitudinal Temperature Variation in Tunnel in Cold Region

Abstract

Based on the high-altitude cold area super-long railway tunnel-Dangjinshan tunnel as the background, this paper studies the temperature distribution and its variation rule in the tunnel through the method of field measurement and theoretical analysis, and obtains the variation rule of tunnel temperature under different temperature conditions at the entrance, as well as the location of 0°C point from the entrance of the tunnel. The conclusions obtained in this paper can be applied to the study of tunnel anti-frost heaving technology and have reference value for the construction of tunnels in cold areas under similar conditions.
