The object of the study is the processes of heat and mass transfer and the parameters of the stress-strain state of the building construction of cable tunnels during a fire. The subject of the study is methods of estimation of fire resistance class of cable tunnel building construction taking into account the real temperature of fire and structural features of the tunnel. Theoretical and experimental researches were carried out: fire tunnel simulation field experiment, computer tunnel fire simulation with parameters similar to the field experiment by means of computer gas hydrodynamics, computational experiments in cable tunnels with different geometric, aerodynamic parameters, and fire load. Also determined the dependence of the temperature of the fire on these parameters.
