| 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. |
| Key words: structured soil,hypoplasticity,solid-liquid coupling,dynamic finite element |
