Tunnels in high-altitude areas in our country have a wide distribution range and a large number. Due to factors such as complex engineering geological conditions and harsh operating environments, tunnels often face severe freezing damage during operation. The freezing damage of tunnels in cold regions often seriously threatens the safety of vehicles. The service level of the tunnel also decreases. This article reviews the typical diseases and manifestations of tunnels in cold regions, this paper analyzes the main causes affecting the freezing damage of tunnels, and finally introduces the common treatment measures for several common diseases of tunnels in cold areas with high altitude, summarizes the main problems of existing treatment measures, and puts forward corresponding improvement measures, which can provide guidance for similar treatment.
