Experimental dependences of the strength of frozen sandy soil on strain rate are analyzed using a structural-temporal approach. Results of dynamic uniaxial compression tests at a temperature of -18oC and strain rates of 400 to 2600 s-1 of frozen sandy soil samples of two types with a mass fraction of ice of 10 and 18% measured at room temperature are presented. The strain rate dependence of the at different temperatures of freezing of frozen sand with a mass fraction of ice of 30% was studied using known experimental data.
