Considering the high temperature problem, this paper details the process of the heat conduction, builds the differential equations of the heat conduction, discusses the boundary conditions. According to the differential equation of the heat conduction, determined the calculation formula of thermodynamic parameters of the heat conduction and get the calculation formula the temperature and interface between the lining and surrounding rock’s calculation formulas. Builded the model of the thermal stress field of the tunnel lining under the high temperature, compiled the calculation program, analyzed the change of the lining’s stress and the influence by the relevant parameters of lining’s stress field under the high temperature.
