ABSTRACT

The highway tunnel in seasonal frozen soil area is experiencing continuous freezing and thawing due to the change of temperature. The phenomenon of frost heave and thaw settlement is frequent, and there are huge potential safety hazards. The prevention and control of frost damage in seasonal frozen tunnel is an important topic in highway engineering research. Thermal insulation method is one of the most widely used frost prevention methods in tunnel construction in cold regions. For highway tunnels in seasonal frozen area, the insulation layer is mainly laid at the tunnel entrance to achieve the effect of repairing frost damage. Taking Zhamutai high-speed tunnel project as an example, combined with field monitoring data, the rationality of thickness and length of insulation layer and its insulation effect are evaluated. The results show that: compared with the initial surrounding rock temperature field without insulation layer, after the insulation layer is laid, the tunnel temperature is generally maintained at about-5 °C, and the tunnel basically eliminates the risk of frost damage; comparing the insulation layers of three different insulation materials, the overall temperature field trend of tunnel surrounding rock is consistent, and the anti-freezing insulation effect is ideal.
