In this study,we predict the relationship between continuous changes in surface temperature about the freezing point and the cycles of freezing and thawing well below the surface,using a method of calculating freezing and thawing at a point below the surface and determining the calculation's accuracy based on changing boundary thermal conditions,which are related to solar irradiation and so on.}, pages = {33--42}, title = {Study on Prediction of Freeze-Thaw Cycles in Concrete Structural Members in Cold Regions}, volume = {24}, year = {1992} }
