Abstract

The basics of the derivation of axial pile capacity based on empirical values and selected results are presented, which are already integrated in the national German recommendations for piles „EA-Pfähle“. The study provides to a large extent a secured range of empirical values for the base resistance and the skin friction for different pile systems as a function of the soil strength. Based on comparative statistical analysis of pile load tests of different pile systems, it becomes possible to derive a consistent analysis of bearing behaviour of pile systems, which provides a safe and an economical pile bearing capacity depending on the expense of preliminary soil investigations.
