| Popis: | This paper intends to clarify the influence of geometric nonlinearity on the behaviour of an embankment built on soft soils, considering the material non-linearity associated with a coupled soil-water formulation. The numerical predictions are compared with the field data in terms of settlements, horizontal displacements and excess pore water pressures. The repercussions of including the large displacements formulation are also studied in terms of the increments of vertical and horizontal effective stresses and of the yield area. It is found that the analysis considering large displacements results in a decrease in settlements and a slight increase in the rate of excess pore pressure dissipation, both of which are related to the reduction of the thickness of a deformable layer. |
