This paper reviews the current status of research on dynamic characteristics of gravel-mixed clay as well as analyzes the influence factors of dynamic shear modulus, damping ratio and dynamic strength. Additionally, it summarizes the numerical method and analytical theory of the materials mesostructure features, as well pointed out that they should be accounted in the research of dynamic characteristics of gravel-mixed clay. Finally, the areas for further research are suggested, i.e., the mesostructure features and influence factors of gravel-mixed clay, the influence mechanism of mesostructure for materials macroscopic dynamic performance, and the micromechanical model based on theory of particle reinforced composite.
