Abstract:To study the variation patterns of the temperature field in seasonal frost region airport subgrades, this research establishes a heat conduction equation with phase change latent heat as an internal heat source. During the freezing and thawing processes in seasonal frost regions, a numerical simulation model of airport subgrades is developed, with thermal characteristic parameters of the soil as research variables. The study focuses on investigating the characteristic changes in the temperature field of season… Show more
