遅延圧密土の一次元変形挙動

Abstract

In the present paper, some theoretical studies are performed from the viewpoint of long-term consolidation, in regard to quasi-overconsolidation behavior of soil known as the Pc-effect. Using the concept of state boundary surface, it is shown that such a soil has anelasitic component with respect to deformation. In spite of above characteristics, the timeeffect for a soil under delayed consolidation and the loading effect for an overconsolidatedsoil are not identical generally, suggesting that the state path for both soils at subsequentloading would be different from each other, even if their start points are the same on thee-log σ'υ plane.
