By using SHPB dynamics experimental systems, studied the different soil moisture content, different permafrost temperature, different conditions, different contingency rate under the stress, and permafrost - Contingency relations law of change in the parameters and their dynamics.

Through uses the SHPB dynamics experiment system, has studied under the different nature of the soil, the different frozen earth temperature, the different water content, the different rate of strain condition, frozen earth stress - strain relations and dynamics parameter change rule.

Dynamics experiment using SHPB system to study different properties, different temperatures, different water content of frozen soil, under different strain rate, stress-strain relationship of frozen soil and its dynamic variation of parameters.
