Frozen soil dynamics is an important part of geotechnical engineering in cold regions,and it is the theoretical basis for studying the earthquake resistance and long-term cyclic load resistance of frozen soil.The development of frozen soil dynamics has achieved fruitful results.This paper mainly introduces the testing methods of frozen soil dynamic parameters,and reviews the research progress of dynamic parameters,dynamic strength,failure characteristics of dynamic creep and dynamic creep strength.The dynamic constitutive model and dynamic creep model are briefly introduced,and finally the development trend of frozen soil dynamics is prospected.
