Excerpt

The concept of fluid flow under consolidation pressure amid micro porous media generated keen interest among several early investigators conceiving effective stresses as early as Terzaghi (1925) and reported by De Boer (2005). The Biot’s (1941) brought significant development to the understanding of 3D consolidation. Along with the progresses in anisotropic consolidation (Kubik 1979; Kubik and Sawczuk 1983), the author offers an impressive set of observations on the rate of consolidation of granular materials. The trends revealed by the paper are, overall, coherent with numerical data on initially isotropic consolidation process bifurcating from 1-D drainage characteristics and tend to adopt 2-D or 3-D drainage. However, owing to depositional and sedimentation dependent anisotropy (Trivedi et al. 2015a) the consolidation process may be anisotropic and resultant deformations can be estimated by a numerically consistent formulation. This discussion focuses on one admittedly minor but nevertheless intriguing result that is the observed differences between 2D and 3D solutions offered by the author and the discusser with few innate similarities and minor differences. …
