Abstract

The Hardening Soil Model has been used to analyse the deformation behaviour of an excavation for an underground car park. Although the excavation is not very deep (about 6.3 m below the surface) it is a very crucial project because of the presence of soft soil layers and the vicinity to existing railway lines. In addition to numerical analyses prior to construction it was decided to refine the analysis during construction utilizing results from in situ measurements obtained in the early stages of construction. Results from these analyses are presented together with measured displacements. It follows from this comparison that the numerical model proved to be a valuable tool in assessing the deformations to be expected at critical phases of excavation.
