Abstract
Finite element step-by-step back analyses were performed on four typical instrumented test sections of several anchored, bored-pile walls, located on the Vransko - Blagovica section of the Celje - Ljubljana motorway. A sufficiently accurate numerical model was obtained in the early stages of the construction sequence, so that it was possible to predict with confidence in advance the critical stages which were encountered at the end of the construction works. The back analyses were carried out using the computer program Plaxis, assuming the simple Mohr-Coulomb constitutive relationship and a simplified geological structure. The results of these analyses were compared with those obtained using the more sophisticated back analyses performed by Vukadin [2001], which took into account the Hardening Soil model and a more detailed geological structure. It was found that, even though the more sophisticated model provided slightly more accurate results, the results obtained by using the simplified model were very similar, which makes the use of such a model and the observational method very attractive for practicing engineers.
