Uniaxial compression and tension tests were conducted on frozen Fairbanks silt at a temperature of -10 C.A relatively stiff testing machine was operated at a constant displacement rate for each test. The tests showed that compressive strength is very sensitive to strain rate and the tensile strength is relatively insensitive to it. The compressive strength increased ten times over a srain rate range of .00012/S to 2.9/s. As was found in other investigations, tangent moduli increased slightly with greater strain rates. The specific eney increased at higher strain rates for compression tests and decreased slightly for tension tests. For increased strain rates, uniaxial compression strength showed no tendency to plateua; nor did the specific energy a minimum during uniaxial tensile testing. (Author).

This new edition of Frozen Ground Engineering gives a peerless presentation of soil mechanics for frozen ground conditions and a variety of frozen ground support systems used on construction projects worldwide. An authoritative update of the industry standard, this Second Edition covers the essential theory, applications, and design methods using frozen ground in the construction of deep shafts, tunnels, deep excavations, and subsurface containment barriers. New material features design models for pavement structures used in seasonal frost and permafrost areas, new information on the movement of fluid phase contaminants in frozen ground, and helpful appendices offering guidance on common frozen ground tests and SI unit conversions. This new edition gives the essential information engineers, geologists, and students need in a complete reference, including up-to-date information on: Sensitivity of frozen ground to climate change Experimental work on frozen soil creep and strength Monitoring creep in frozen slopes Frost protection of foundations using ground insulation Highway insulation Load restrictions for seasonal frost areas

Uniaxial constant-stress and constant-strain-rate compression tests were conducted on more than 200 remolded, saturated, frozen specimens of rates show a close strength correspondence between the constant-stress and constant-strain-rate tests. All of these complete stress vs strain rate curves could not be described by a single power law or exponential equation, indicating that different deformation mechanisms are dominant within different ranges of strain rate.
