Fig. 4. Representation of (a) the shrinkage curves, in the void ratio–water content (e–W) diagram, of 1.65- (), 1.80- () and 1.96-m-deep (•)intact samples (lozenges = fraction <400 µm, full straight line = e linear regression calculated in the 20 to 40% W domain, ZS = zero shrinkage, RS = residual shrinkage, PS = proportional shrinkage, SS = structural shrinkage); and (b) height–water content of the intact samples (full curved line = polynomial height calculation according to the isotropic shrinkage, W_s = shrinkage limit, W_p = plasticity limit).
