One-Dimensional Computer Models to Estimate Frost Depth

The impacts and detrimental effects of frost in regions that experience seasonal variation are well documented. The effects of successive freezing and thawing cycles on soil and other substrates, as well as vehicle mobility through the surface-vehicle interface, play a prominent role in transportation. Freezing and thawing are not limited to only geographic locations that experience severe and prolonged cold; even brief periods of low temperatures or freeze-thaw cycling can disrupt transportation operations. At selected locations in North Korea, the depth of frost penetration was estimated using a one-dimensional heat flow model based on the Modified Berggren solution. At one of the locations, the progression and duration of frost penetration over five successive freezing seasons was estimated using a separate one-dimensional heat and moisture flux model. With uncertainties regarding climate change under consideration in design and operations, this type of analysis is even more crucial. A spreadsheet and graphical user interface (GUI) are proposed for ease-of-use by persons unfamiliar with thermal analysis and heat transfer in soils. A tool of this type would lead users through the necessary calculations and assumptions.
