Abstract
Based on Biot's three-dimensional consolidation theory of porous media,
analytical solutions of the transient consolidation deformation due to
a point sink in a saturated isotropic porous elastic half-space are
presented. Using the Laplace, Hankel and Fourier integral transform
techniques, closed-form solutions of the horizontal and vertical
displacements of the ground surface are obtained. In the analysis, case
of permeable half-space boundary is studied. The consolidation as
effected by the soil parameters are illustrated and discussed.
