%X Frozen soil samples at 4 different temperatures were investigated in 4 different high strain rates on Split Hopkinson Pressure Bar (SHPB). The test results indicated that temperature and strain rate each have an effect on floating stress, this shows the time-temperature equivalence property of frozen soil. And the time-temperature equivalence property also show its dynamic brittleness and frozen brittleness. The oscillation and convergence of strain-stress curves are also aroused by its time-temperature equivalence property.
