Abstract:
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 -18$^\circ$C 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.
Keywords:
frozen sandy soil, strength, strain rate, mass fraction of ice.
