ABSTRACT: The dynamic response of frozen soils is one of the significant factors that should be taken into account when designing and constructing infrastructures in cold regions. This paper firstly reviews the state-of-the-art dynamic testing techniques including dynamic uniaxial/triaxial test, resonant column test, wave velocity test and the SHPB test. Then the correlations of dynamic indexes for frozen soils with test conditions are analyzed i.e., dynamic modulus, dynamic strength, damping ratio as well as dynamic Poisson’s ratio. The typical stress-strain relationships for frozen soils under dynamic loading are summarized such as empirical models, creep modeling and strength criterion for frozen soils. Finally promising prospects of the study in this paper is suggested.
