AbstractSubstantial quantities of water remain unfrozen in soils at temperatures of several degrees below 0°C. The proportion of unfrozen water decreases as the temperature is lowered, but as much as half of the water may exist unfrozen at -1°C. This unfrozen water has been attributed to the suctions or negative pore pressures that develop as a result of ice-lens growth in the soil. A negative pore pressure in a saturated soil, in the absence of external loading, results in a positive effective stress (a stress acting across the grain - to-grain contacts) equal to the negative pore pressure. An increase in effective stress causes consolidation in compressible soils.
