Experimental assessment of the effect of frozen fringe thickness on frost heave
A frozen fringe plays a key role in frost heave development in soils. Previous studies have focused on the physical and mechanical properties of the frozen fringe, such as overall hydraulic conductivity, water content and pore pressure.

Frost heave model calculations for the Calgary frost heave test facility
Frost heave calculations using the Segregation Potential (SP) model and the Incremental Ice Segregation (DISR) model are compared ta the observed frost heave data from chilled pipeline sections at the Calgary Frost Heave Test Facility. Madel calculations are performed with the measured temperature gradients and measured frost depths for a range of SP ...

Geocomposite capillary barriers to reduce frost heave in soils
We investigated the potential for geosynthetic capillary barriers to reduce frost heave in soils by freezing upright, cylindrical soil specimens with horizontal disks of geosynthetics placed in them.

A Note on the Frost Heaving of Rocks
For the purpose of forecasting the frost heaving of rock masses, the author studied on the relation between the rate of frost heaving and physical properties of rocks such as grain size distribution, specific gravity, water contents, etc. Laboratory tests were carried out to rock specimens which are molded into a cylinder with the height of 3 cm and ...
