Title: | Analysis of a braced excavation in soft soils considering the consolidation effect |
Issue Date: | 2007 |
Abstract: | The studies of excavations in soft clayey soils are normally based on undrained total stress analyses. A better approach consists of taking into account the effects of consolidation during the excavation-bracing process and after the completion of the construction by means of coupled finite element analyses in effective stresses. In this paper, the geotechnical behaviour of a braced excavation in the soft soils of San Francisco (USA) is analysed, both during and after the construction period. Numerical analyses are performed with a finite element program, which incorporates the Biot consolidation theory (coupled formulation of the water flow and equilibrium equations) and soil constitutive relations simulated by the p-q-Î, critical state model. Numerical results are compared with field results. Â(c) Springer Science+Business Media B.V. 2007. |
