Abstract:	Fertigschraubpfähle werden mit hydraulischen Geräten drehend in den Boden eingebracht. Die Herstellungsart bietet Zeit- und Kostenvorteile gegenüber Ortbeton- und Verbundbauweisen. Zur Untersuchung der bodenmechanischen Vorgänge beim Abtrag von axialen Lasten durch Fertigschraubpfähle wurden kleinmaßstäbliche 1g-Versuche unter Anwendung der PIV-Methode durchgeführt. Die Ergebnisse werden vorgestellt und mit Ansätzen zur analytischen Berechnung der Tragfähigkeit aus der Literatur verglichen. Den Erkenntnissen aus den Modellversuchen werden Beobachtungen aus großmaßstäblichen Laborversuchen und Feldversuchen gegenübergestellt. Abschließend werden Empfehlungen für die Bemessung und Qualitätssicherung gegeben. Bearing behaviour of helical piles under axial loading Helical piles are rotating installed into the ground using hydraulic equipment. This method of construction offers time and cost advantages over bored piles. Small-scale 1g tests using the PIV method were carried out to investigate the soil mechanical behavior that occurs due to axial loading. The results are presented and compared with analytical approaches for the calculation of the bearing capacity from literature. The results of the model tests are compared with observations from large scale laboratory tests and field tests. Recommendations for dimensioning and quality assurance are given in conclusion.
