Artificial Neural Network-Based Model for Prediction of Frost Heave Behavior of Silty Soil Specimen
Applied Sciences, 2021 Frost heave action is a major issue in permafrost regions that can give rise to various geotechnical engineering problems. To analyze and predict this phenomenon at a specimen scale, this study conducted a fully coupled thermal-hydro-mechanical analysis ...

Frost Heave in Colloidal Soils [PDF]
SIAM Journal on Applied Mathematics, 2011 We develop a mathematical model of frost heave in colloidal soils. The theory accounts for heave and consolidation while not requiring a frozen fringe assumption. Two solidification regimes occur: a compaction regime in which the soil consolidates to accommodate the ice lenses, and a heave regime during which liquid is sucked into the consolidated soil

Topics in Cognitive Science, EarlyView., 2023 Abstract Over the past three decades, Van Gelder's dynamical hypothesis has been instrumental in reconceptualizing the ways in which perception‐action‐cognition unfolds over time and in context. Here, I examine how the dynamical approach has enriched the theoretical understanding of social dynamics within cognitive science, with a particular focus on ...

A frost heave model of unsaturated coarse-grained soil considering vapour transfer [PDF]
E3S Web of Conferences, 2020 Substantial frost heave has been observed in coarse fills in high-speed railway embankments. These coarse fills have low fine contents and very low water content. The groundwater table is located below the coarse fills.

Incidents of damage to berm drainage ditches in cold region and countermeasures [PDF]
MATEC Web of Conferences, 2019 Berm drainage ditches may fail due to frost heave in cold and snowy areas like Hokkaido. Many of these failures are regarded to be caused by damage due to frost heave in the ground or freeze-thaw, but no sufficient measures are being taken, as ...

Journal of Glaciology, 2010 AbstractThe deformation of the ground surface that is produced by frost heave has motivated almost a century of concerted laboratory, field and theoretical studies. Well before the development of equipment capable of resolving the microscopic films that support liquid transport towards growing ice lenses, early investigators predicted their occurrence ...
