Frost-resisting problem is important for the tunnel in cold region, and thus some thermal protective measure are necessary in order to avoid potential frost. With the development of land transport, tunnels plays an important role in the improvement of land transportation, so it is urgent to prevent the freezing and thawing of tunnel in cold region. In this paper, the temperature field of Jinzhangzi tunnel is chosen as a target project, and corresponding three protective measure are taken into account. There are four cases are considered respectively. Including the unprotected, the active heating system, passive thermal insulation system and hybrid thermal protective system. Especially, the hybrid thermal protective system maybe the cost efficient.
