Vous connaissez sans doute Burj Dubaï,( et le site officiel de la tour) du moins en photo, ce gratte ciel en construction à Dubaï, qui vientd'atteindre, le 20 mai 2008, une hauteur de 649.7 mètres ce qui en faitla plus haute construction jamais construite à ce jour.

Et visiblement la construction n'est pas finie car, elle devrait atteindre les 850 mètres de haut.

La photo ci dessus, représentant Burj Dubaï, fait vraiment penser à une attraction posée au milieu d'un fête foraine.

the principles of piled raft foundation design and outlines thecircumstances in which they can provide an economical alternative toconventional piled foundations. The foundation design process adoptedfor the Burj Dubai, the world’s tallest building, is then described.The foundation system is a piled raft, founded on deep deposits ofcarbonate soils and rocks. The paper discusses the geotechnicalinvestigations undertaken, the field and laboratory testing programs,and the design process, and how various design issues, including cyclicdegradation of skin friction due to wind loading, were addressed. Thenumeral computer analysis that was adopted for the original design,together with the check/calibration analysis will be outlined, and thenthe alternative analysis employed for the peer review process will bedescribed. The paper sets out how the various design issues wereaddressed, including ultimate capacity, overall stability under windand seismic loadings, and the settlement and differential settlements.

The comprehensive program of pile load testing that was undertaken,which included grouted and non grouted piles to the maximum load of64MN,will be presented and ‘’Class A’’ predictions of the axialload-settlement of the towers observed during construction will becompared with those predicted.
