Abstract

Abstract

An alternative analytical technique to study a plane strain consolidation of a poroelastic soil by taking into account the anisotropy of permeability was presented. From the governing equations of a saturated poroelastic soil, the relationship of basic variables for a point of a soil layer was established at between the ground surface (z=0) and the depth z in the LaplaceFourier transformed domain. Combined with the boundary conditions, an exact solution was derived for plane strain Biot's consolidation of a finite soil layer with anisotropic permeability in the transform domain. Numerical inversions of the Laplace transform and the Fourier transform were adopted to obtain the actual solution in the physical doma in. Numerical results of plane strain Biot's conso lidation for a single soil layer shows that the an isotropy of perm eability has great in fluence on the consolidation behavior of the soils.
