Chinese researchers recently investigated the evolution features of dynamic stiffness parameters in the small strain range to determine the effects of freeze-thaw cycles on the dynamic responses of frozen subgrade soil, providing an important reference for assessing the degeneration of engineering properties for frozen subgrade soil exposed to freeze-thaw cycles.
