On Relation between Frost Penetration and Frost Heave

Journal of the Japanese Society of Snow and Ice, 1965
Frost heave and its damages are the most important factors affecting road in a cold area.Neumerous data have been obtained from the investigation of frost penetration and heaving of roads in all parts of Hokkaido over a period of several years.This paper contains following items.(1) Relationship between frost penetration and freezing index.(2 ...

Absence of Pressure-Driven Supersolid Flow at Low Frequency

, 2009
An important unresolved question in supersolid research is the degree to which the non-classical rotational inertia (NCRI) phenomenon observed in the torsional oscillator experiments of Kim and Chan, is evidence for a Bose-condensed supersolid state with

Frost Heave of Irrigation Canals in Seasonal Frozen Regions

Advances in Civil Engineering, 2019
Soil frost heave acts as a driver of the emerged fracture in the concrete lining of irrigation canals and subsequent water leakage in seasonal frozen ground. A model test was carried out on the frost heave of a U-shaped canal with concrete lining.

Spatiotemporal Mechanical Effects of Framework–Slope Systems Under Frost Heave Conditions

Applied Sciences
To investigate the slope instability caused by differential frost heaving mechanisms from the slope crest to the toe during frost heave processes, this study takes a typical silty clay slope in Xinjiang, China, as the research object.

Research on the Mechanism of Frost Heaves Caused by Void Water Accumulation behind the Lining of High-Speed Railway Tunnels in Cold Regions

Applied Sciences
(1) Background: Lining voids and macroscopic water freezing are both prominent issues that threaten driving safety in high-speed railway tunnels. With the continuous expansion of the scale of high-speed rail tunnels in extremely cold areas in China, the ...

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

Freeze, thaw, fracture? [PDF]

, 2007
Why does freezing break up rock? Everybody knows that when water freezes it expands by nine percent to be precise. If it seeps into rocks and then freezes, the rocks can fracture and split apart, a process known as frost weathering.
