Mechanical behavior assessment of retaining wall structure due to frost heave of frozen ground

International Journal of Geo-Engineering
Frost heave action is a major issue in permafrost regions, leading to various geotechnical engineering problems. In this study, we assess the mechanical behavior of a concrete retaining wall subjected to frost heave under different ground conditions. The

Estimation of frost heave for stratified soil profile

, 1994
An operational model for estimation of frost heave in field where stratified soil profile occurs is presented. The model is developed from the research model described and verified by Sheng and Knutsson (1993). Soil layers are first classified into frost-

Effect of fines content on frost heave

, 1996
In regions of seasonal frost the integrity of pavement structures is dependent on the resistance of base and subbase soils to frost action. This note describes the results of performing the U.S.

The Distribution Characteristics of Frost Heaving Forces on Tunnels in Cold Regions Based on Thermo-Mechanical Coupling

Applied Sciences
To address the freezing damage to tunnel lining caused by frost heaving of the surrounding rock in water-rich tunnels in cold regions, a numerical thermo-mechanical coupling model for tunnel-surrounding rock that considers the anisotropy of frost heave ...

Frost-heaving in soils

, 1966
A literature survey shows that present interest in frost action research is focused on thermodynamic properties of the ice-water interface. This aspect of the freezing process is a fascinating field for research and much progress is being made, but there are many other equally important aspects, when ice-lensing is involved in the freezing process.

THE EXPERIMENTAL CHARACTERIZATION AND NUMERICAL MODELLING OF FROST HEAVE

, 2015
Frost heave is the expansion of soil upon freezing due to the formation and growth of segregated ice lenses. Because of the large stresses and displacements associated with frost heave, it is an import design consideration for geotechnical structures ...

Differential Frost Heave in Seasonally Frozen Soils

, 2007
The formation of some forms of patterned ground, notably earth hummocks and stone circles, is associated with seasonal freezing and a spatial instability in the resulting frost heave.
