| 摘 要： | 
In areas with seasonal freezing, when the tunnel lining concrete is saturated with water infiltrating the interior, the lining and the surrounding rocks will simultaneously freeze.However, the current calculation of the frost heaving force fails to consider the synchronous damage to the lining and surrounding rocks under freeze–thaw cycles. Therefore, as per the elastic calculation model of the frost heaving force and model of steady-state heat transfer of circular tunnels, this study introduces.
