ABSTRACT: The new Klagenfurt stadium and the adjacent gymnasium and soccer academy
comprising a capacity of 32,000 spectators were constructed from 2006 to 2007 for the
European Soccer Championship EURO 2008. The ground properties are predominated by
saturated soft clays, silts and sands. The underlying bed rock was found in different depths,
thus, the thickness of soft soils varies from about 30 to 80 m. The ground was improved by
installing stone columns using the vibro replacement technique up to about 18 m, thus
homogenizing the ground conditions in the upper layers. Nevertheless, large settlements in
the range of up to 15 cm were predicted due to the large foundation area and high loads
affecting the ground up to about 60 m. During construction and current long-term settlement
measurements have been performed to record the time-dependent deformation behaviour of
the ground. Moreover, a well instrumented field trial was carried out during construction. The
instrumentation consisted of multilevel-piezometers, multilevel-extensometers and earth
pressure cells as well as a horizontal inclinometer. Semi-analytical and numerical simulations
using constitutive models were performed to calculate the settlement process and final
settlements. Actual settlement measurements show both consolidation and probably
creeping behaviour of the soil as well. Calculations based on a sophisticated constitutive
model have been applied in order to take into consideration the observed soil deformations.
