Abstract: 

Description of time dependent deformation of soils in terms of visco-elastic models is a useful method that can be employed to improve many deficits of current conventional methods of evaluation of soil consolidation behavior. In this research creep behavior of different soil specimens are evaluated and it is shown that the secondary consolidation behavior may be well defined with the generalized Maxwell visco-elastic model. Several consolidation tests on different remolded and undisturbed soil specimens were carried out and time dependent behavior was studied. The dependency of constants of the generalized Maxwell model on the effective stress level and also dependency of creep settlement pattern on the variations of constants of the proposed model were appraised. It was concluded that the proposed model is an effective and useful tool for defining of complete settlement behavior explicitly in long term.
