“…ll), lie between the present lines for -10 and -15°C and parallel to them. The data of Ladanyi and Arteau (1978) for -5°C fall consistently below the present line for -6°C; however, they also find a linear increase of strength with increasing strain rates on a log-log scale, for a wide range of strain rates.…”

Geotechnical Journal, 17, 1, pp. 74-88, 1980-02 Deformation behaviour and strength of frozen sand Parameswaran, V. R. Uniaxial unconfined compression tests were carried out on frozen saturated Ottawa sand containing about 20% by weight of water, at temperatures between -2 and -15"C, and at strain rates varying between and 10-2 s-l. The compressive strength and the initial tangent modulus increased with increasing strain rate and with decreasing temperature. At -2"C, values of strength and modulus were considerably lower than those predicted by linear extrapolation of the values observed at lower temperatures, on a log-log scale. This could be due to the presence of unfrozen water in the samples at -2°C. Canadian National Research Conseil nationalDes essais de compression simple ont Ct C faits sur du sable d'Ottawa gelk, sature B une teneur en eau de 20%, sous des tempkratures de -2 B -15"C, et B des vitesses de deformation variant de 10-7 B 10-2 s-l. La resistance en compression et le module tangent initial augmente avec une augmentation de la vitesse de deformation et une diminution de la temperature. A -2"C, les valeurs de la resistance et du module sont considerablement plus faibles que celles deduites d'une extrapolation linhire sur une khelle log-log des resultats obtenus B plus basse temperature. Ceci peut Stre dii B la presence d'eau non gel& dans les khantillons B -2°C.[Traduit par la revue] Can. Geotech.
