“Frost Heave – Nature’s Entrepreneurial Challenge for Arctic Infrastructure” highlights the significant threats posed by permafrost degradation to infrastructure in the Arctic region.

Frost heave, a natural phenomenon involving the volumetric expansion of water upon freezing, can seriously affect land transportation networks and construction projects.

Numerical simulations and improved modeling approaches are crucial for accurately assessing the risks associated with future damage and implementing appropriate mitigation measures to address this critical challenge.

Frost heave can generate ground uplift forces exceeding 10 tons per square foot, posing a significant threat to the structural integrity of Arctic infrastructure such as roads, pipelines, and buildings.

The rate of frost heave can reach up to several inches per day, rapidly altering the landscape and causing damage to critical transportation networks in the Arctic.

Certain soil types, such as silty soils, are particularly susceptible to frost heave due to their high capillary action, which draws moisture from the ground and facilitates the formation of ice lenses.
