摘要：
One-dimensional consolidation tests on clay have been performed using a one-dimensional model which can consider the effects of density, bonding and time. The model can explain strain rate effect, stress relaxation characteristics and creep characteristics of soils comprehensively without fitting the model for a particular phenomenon. The model can also describe other characteristics of soils such as secondary compression, delayed consolidation and consolidation characteristics of naturally deposited soils. Here, consolidation behavior of clay has been investigated varying the density of soil having different states of bonding. Varying the thickness of soil samples, the dependency of the sample height on the consolidation behavior has been checked as well. It is found that the model can explain well the behavior of secondary consolidation of naturally consolidated soil, overconsolidated soil and structured soil.
