| Abstract: | The one of important mechanical properties of soft clay is the time dependent behaviors,which is depended on its viscosity and consolidation. Based on considering their interaction, a visco elastic plastic finite element model of Biot′s consolidation is presented in this paper,to describe the soil deformation and neutral pressure variation of preloaded soft foundation. And through an practical example, the coupled effect of creep and consolidation on deformation of ground are studied. |

| Keywords: | visco elastic plasticity Biot′s consolidation constitutive relation finite element analysis |
