Properties of Embankments Constructed in Winter
In snowy, cold regions, embankments constructed in winter may cause settlement and collapse of slopes in the thawing season in early spring. One of the reasons may be unavoidable suspension of the work due to work schedules while constructing an embankment during a cold winter. Accordingly, assuming such construction, 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: (1) even in a 30-cm-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; and( 4) when the embankment freezes, the density and water content decrease.
