Abstract
The oedometer tests of remoulded deep clay in East China subjected to consolidation stresses ranging from 0.2 to 15.0 MPa were carried out. Both the measured compression curves and the curves of logarithmic permeability versus void ratio consist of two linear segments, among which the bilinear shape of the compression curves is less noticeable. The consolidation stress and void ratio at the intersection of two lines are around 2 MPa and 0.565 ± 0.015, respectively, and the corresponding saturated water content is very close to the reported saturated adsorbed water content. Lastly, but most importantly, the calculated microscopic pore size corresponding to the intersection point agrees well with the transitional range of the distance between two clay surfaces within which water molecules transform from bulk-liquid-like water into confined water. This is confirmed by experimental results available in the literature.
