Abstract: The results from previous investigations of frozen soils indicate: (1)Dynamic stress-strain properties for coarse-grained soils can be nearly an order of magnitude greater than for fine-grained soils, and energy absorbing properties can vary significantly with soil type and composition; (2)over a range of void ratios from 0.3 to infinity (ice) dynamic stress-strain properties for fully saturated soils can decrease by a factor of 5; (3)dynamic stress-strain properties of frozen soils increase with increasing degree of ice saturation; (4)the same properties decrease and damping properties increase with ascending temperature; (5)the same properties decrease and damping properties increase with increasing axial strain amplitude from 10-³% to 10-¹%; (6)the frequency of loading has only a minor effect on dynamic stress-strain properties, and the effect on damping properties may be important at low frequencies; and (7)confining pressure has an important effect on the dynamic properties of coarse-grained soils and a relatively unimportant effect on fine-grained soils.
