Abstract
In order to clarify consolidation behavior of clay ground under cyclic loading, a series of cyclic triaxial consolidation tests was carried out for clay samples cured at a high temperature, whose mechanical properties are similar to those of undisturbed natural clay samples, and for usual clay samples cured at the room temperature. The pre-consolidation in the triaxial tests was carried out under K0 condition to simulate the consolidation history of naturally deposited clay ground. As the results, it was found that it makes differences to the cyclic triaxial consolidation behavior not only whether the used sample is the high temperature cured sample or the room temperature cured sample but also whether the pre-consolidation process in the triaxial tests is K0 or isotropic consolidation. It was also found that both of volumetric and shear deformation under cyclic loading are much larger than those under static loading in the case where the load just over the consolidation yield stress was applied to the clay sample reconsolidated at the high temperature and pre-consolidated under K0 condition.
