"Ground improvement versus hybrid foundation and deep foundation - comparison of foundation concepts for three case histories of European significance";
Keynote Lecture: Geo Projects 2014, Sofia (invited); 2014-10-15 - 2014-10-17; in: "Proceedings of Geo Projects 2014", (2014).

The focus of the keynote paper is on the co
mparison of different
foundation concepts
for three case histories of European significance.
The stadium in the Austrian city of Kla
genfurt was designed and built for the EURO
2008 (Austria and Switzerland) in slightly
consolidated soft lacustrine clays. The
shallow foundation rests on floating sto
ne columns installed with the vibro
replacement technique allowing contro
lled large time-dependent settlements.
For the Combined Cycle Power Plant Malzeni
ce near Bohunice (S
lovakia) a hybrid
foundation concept was executed in collaps
ible aeolian silt deposits (loess). The
ground was initially improved by the vibr
o replacement technique and the final
cementation of the stone column
s produced deep foundation elements.
The new spectacular cable-stayed bridge over
the Sava River is the new landmark of
Belgrade (Serbia). The 200 m tall pylon of
the 965 m long bridge rests on a closed
box foundation made of a cl
asping diaphragm wall and la
rge-diameter bored piles
inside. Thus, the highly concentrated l
oads are deeply transferred into the over-
consolidated marls.
The different foundation concepts are com
pared and discussed. It is illustrated that
all the concepts are justified taking into ac
count the ground conditions, structural and
serviceability requirements of
the buildings, and economical
factors (time and cost).
