Two Dimensional Consolidations for Clay Soil of Non-Homogeneous and Anisotropic Permeability

Ressol R. Shakir, Muhammed Majeed

Abstract: In this research a computer program was modified to solve two-dimensional consolidation problems. The modified computer program results showed a very good agreement compared with the analytical solution of two-dimensional consolidation. The non-homogeneity in one and two directions with the an-isotropic effect of permeability was included in the program. It was found that the increasing of anisotropic ratio of permeability increases the average degree of consolidation while the increase in non-homogeneous permeability ratio decreases the average degree of consolidation according to the drainage face taken there. This effect should be taken in to account when dealing with the analysis of consolidation of compressible soil and average degree of consolidation.
