Abstract

A set of triaxial constant strain rate and constant stress tests was performed on artificially frozen soil samples to study the effect of the volumetric ice fraction, strain rate and also confining stress on the mobilized shear strength. In general, the peak shear strength increased with decreasing volumetric ice content and increasing strain rate. The tests showed the dependency of the mechanical failure and deformation mode of frozen soils on the loading conditions. Such investigations on artificially frozen soils samples may help in developing a better understanding of rock glacier and general permafrost dynamics at temperature close to the melting point of ice
