| Abstract: | The hypoplasticity disturbed-state-concept model for structured soil and unsimultaneous staggered iteration finite element method (FEM) with explicit difference scheme are proposed. The dynamic solid and liquid coupling responses of a simple saturated sand soil are calculated by use of the model and FEM calculating program of Biot dynamic consolidation. |

| Keywords: | structured soil hypoplasticity solid-liquid coupling dynamic finite element |
