Soil microstructure, thermal, hydraulic and other properties and ground behaviour in cold regions.

Author(s) : WHITE T. L., WILLIAMS P. J.

Summary

The microstructure of freezing soils is largely responsible for their properties and behaviour. Experiments have shown how the microstructure is modified by freezing and, in turn, that the microstructure controls physical and geotechnical properties of the material. The microstructure of a soil controls the relative free energy of the soil water as a function of water content. This results in the dependence of unfrozen water content on temperature. These points are studied, the target being to be able to predict the evolution of soil conditions over periods of years, which is very important in the cold regions.
