| Abstract: | Analytical solutions for the consolidation calculations of a semi-infinite space with impeded boundaries are derived. Laplace and Hankel integral transforms are utilized. Two boundary-value problems involving unit point loading and ring loading in the vertical are considered. The solutions are extended to circular distributed normal load. The computation and analysis of settlements, vertical total stress and excess pore pressure in the consolidation layer subject to circular loading are presented. |
