Abstract
In snowy cold regions, embankments constructed in winter may have settlement and collapse of slopes in the thawing season in early spring. One of the reasons may be unavoidable suspension of the work sequence for constructing an embankment during a cold winter. Accordingly, assuming such work condition, a test construction was conducted in the winter season. For the constructed embankment, its inside temperatures and strength were measured. Also, after the embankment melted it was cut open and the density and water content were measured. As a result, it was found that. The results of this study can be summarized as follows: 1) even in a 30cm high embankment, frost and moisture movement occur, 2) a frozen embankment is strong but a non-frozen one is not strong, 3) depending on the embankment construction method, layered frost remains and the number of layers increases with the increase of construction days, 4) when the embankment freezes the density decrease, 5) that the laying of insulating material is very effective a controlling freezing.
