    Abstract
  • In order to determine the optimum thickness of antifreezing layer of highway tunnel in cold region, the thickness was computed by separately using equivalent thickness conversion method, weather analytic method and finite element simulation method.Calculation result shows that aimed at former two kinds of methods, the antifreezing layer thickness is less than 1 cm when it lies between the primary support and the lining, and less than 2 cm when it lies on the lining surface, which are consistent with the practice; the relevant values are 3.2 cm and 4.4 cm respectively aimed at finite element simulation method, which are bigger than the thicknesses of antifreezing layer in reality; the result of finite element simulation calculation is excessively safe for the structure, the computation process of weather analytic method is complex, the computation process of equivalent thickness conversion method is easy and can be applied in engineering practice; the antifreezing layer is suitable to be laid between the primary support and the lining to save money.
