On the Deformation Behavior of Soil under Delayed Consolidation

Abstract

In the present paper, some theoretical studies are performed, from the viewpoint of a long-term consolidation, in regard to the quasi-overconsolidation behavior of soil known as the pc-effect. Using the concept of a state boundary surface, it is shown that such soil has an elastic component with respect to deformation. In spite of the above characteristics, the time effect for soil under delayed consolidation, and the loading effect for overconsolidated soil are generally not identical. This suggests that the state paths for both types of soil at a subsequent loading would be different from each other, even if their starting points are the same on the e-log σ￥_v plane.
