| Abstract: | The main instruments for soil dynamic indoor tests and their characteristics were summarized. The trend of and some key points in their development were presented, i.e. the expansion of test materials, research of soil dynamic properties under complicated stress state, acquirement of soil dynamic parameters under small strains, and some influencing factors on dynamic intensity, liquefaction and dynamic parameters. The basic concepts of dynamic intensity and liquefaction were further discussed, and some advances in the dynamic constitutive model were also reviewed. |

| Keywords: | soil dynamic indoor test complicated stress dynamic intensity soil liquefaction dynamic constitutive model |
