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

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

Evolution Patterns of Frost-Heaving Pressure with Partial Ponding in Cold Region Tunnels
Geofluids, 2022 The calculation of the frost-heaving pressure is one of the key issues in the frost-resistant design of tunnels in cold regions. To reveal the frost heave mechanism of partial ponding behind the tunnel linings, a three-dimensional geo-mechanical model ...
