Abstract:     
 
Anhand einer statistischen Auswertung dynamischer Pfahlprobebelastungen und zugehöriger Drucksondierungen wird ein neues Nachweisverfahren der vertikalen Tragfähigkeit für Spundwände vorgestellt, das in die 11. Auflage der EAU eingehen wird. Es wird gezeigt, dass die mittels Pfahlprobebelastungen ermittelte Gesamttragfähigkeit in nahezu allen Fällen die rechnerische Tragfähigkeit übersteigt. Das Nachweisverfahren wird hiermit der Fachwelt vorgestellt und diese wird aufgefordert, den Autoren Daten aus dynamischen Pfahlprobebelastungen und zugehörigen Drucksondierungen zur weiteren Validierung des Nachweisverfahrens zur Verfügung zu stellen.

Revision of the verification procedure for vertically loaded sheet piles of the EAU.
On the basis of statistical evaluations of dynamic pile tests and corresponding cone penetration tests, a new verification procedure for vertically loaded sheet piles is introduced. It is shown, that the real bearing capacity of nearly all tested sheet piles is higher than the calculated bearing capacity. By this paper, the new verification procedure is presented to the concerned professional's public. The authors encourage professionals to provide data of dynamic pile tests and corresponding cone penetration tests for further validation of this new approach.
