NONLINEAR CONSOLIDATION THEORY FOR NONHOMOGENEOUS CLAY LAYERS AND ITS APPLICATION

概要

The first author derived a generalized one-dimensional consolidation theory in 1961 involving strain that takes into account the changes in m_v, K, consolidation pressure and the depth of the clay layer (finite strain), during the consolidation process, and the effect of the selfweight of clay. This theory, however, applies only to clay layers with uniform consolidation properties ; it has limited applicability to clay layers in the field, which are usually composed of different soils. The consolidation theory was thus amended to account for the continuous change in consolidation properties along the depth. The derivation of this consolidation theory is detailed, and two examples of application to thick alluvial clayey layers in the Osaka Port area together with comparisons with field observations are presented.
