Abstract


In this work the consolidation characteristics of the experimental and theoretical was studied. The analyses was carried out on the basis of the axial soil deformation progress and pore pressure dissipation. The aim of this research was to put some light on the quasi-filtration phase of consolidation. The results of consolidation studies on five high quality paste samples prepared from krakowiec clay showed that the quasi-filtration occur only in specific stages of the whole process. The analysis of changes in consolidation coefficient depending on the degree of consolidation enables the separation of the region of quasi-fixed values cv.
