Secondary frost heave in freezing soils. [PDF]

open access: yesSIAM Journal on Applied Mathematics, 1989
Summary: A mathematical model of secondary frost heave in freezing, gravelly soils is presented. This model is due to \textit{K. O'Neill} and \textit{R. D. Miller} [Water. Resour. Res., 21, 281-296 (1985)], who sought numerical solutions. Here, their model is made nondimensional and is analyzed using asymptotic analysis.

Study on discrete prediction model for mechanical behavior of buried pipelines under the influence of differential frost heave [PDF]

open access: yesScientific Reports
Pipelines are the primary mode of oil and gas transport in cold regions. Differential frost heaving of frozen and non-frozen soil masses can damage such pipelines, posing economic and environmental risks.

Experimental study on the evolution characteristics of cyclic frost heaving pressure of saturated fractured granite

open access: yesRock and Soil Mechanics, 2021
The frost heaving pressure generated by water–ice phase change and volume expansion of saturated fractured rock mass in cold regions promote the initiation and expansion of new fractures, and lead to further damage and deterioration of fractured rock ...
