Abstract

The basics of the derivation of axial pile capacity based on empirical values and selected results are presented. Empirical values for both base and shaft resistances based on soil strength, e.g. the resistance of cone penetration tests or the undrained shear strength, are derivated for a range of commonly used pile systems. Up to 1000 pile load tests on displacement piles, such as precast concrete, cast in place, steel, and screwed cast in place piles, etc. and micro piles are evaluated. The result of this study has been already integrated in the national German recommendations for piles “EA-Pfähle”.
