Abstract: The results of dynamic frozen soil tests are difficult to find in the Russian scientific publications. However, frozen soils dynamic characteristics can affect the operation of buildings. Russian researchers have little test experience, no proper equipment and research methods. And that does not allow them to obtain accurate dynamic properties of frozen soils. To study this issue, a series of articles has been prepared, the first of which shows the dynamic properties of frozen soils on the basis of resonant column tests, presents a literary review of foreign scientists’ publications on the considered topic from 1960–1980 to the present time, their analysis and generalization. The article shows the influence of temperature, humidity, composition, density and vibration amplitude of frozen soil on its dynamic shear modulus and damping ratio. A comparison of the dynamic properties of frozen soils and unfrozen ones is made, the influence of the temperature of frozen soils on their dynamic characteristics is estimated. At low negative temperatures that are from minus 10 °C to minus 3 °C, dynamic shear modulus is on average 3000–900 MPa, at temperatures that are higher than minus 2 °C its value decreases to 500–90 MPa. The damping ratio of frozen soils at a temperature of on average minus 5 °C and higher is 0.08–0.12, at a temperature of minus 10 °C and lower it is 0.05–0.07.

 

Keywords: frozen soil; dynamic properties of frozen soils; resonant column tests; dynamic tests; damping ratio; laboratory testing; permafrost zone (cryolithozone).
