Description: Research Report
Summary: Laboratory studies on the effects of the soil-temperature regime on the type of ice segregation and the rate of frost heaving are described in detail, and the results are analyzed quantitatively on the basis of thermodynamic and hydraulic theory, assuming that suction is created by ice formation. The heaving rate varied with the type of ice segregation, which in turn depended on the rate of frost penetration. Ice-filament layers or sirloin-type freezing were observed at low penetration rates and concrete-type freezing at high penetration rates. The heaving rate decreased with increasing frost-penetration rate, and varied, in the case of filament-type freezing, according to the amount of sensible heat lost at the freezing interface. The sensible heat loss was 0.62 cal/cm-sec in the case of maximum heaving (7 mm/day); higher values resulted in thermal conditions favoring sirloin-type freezing. The moisture content of frozen soil was found to be related to the heaving ratio, inasmuch as the amount of heaving is attributed to the amount of segregated ice.
