This paper deals with the analysis of results from axial testing of vertical single piles, i.e. the most common field test performed. Despite the numerous tests which have been carried out and the many papers which have reported on such tests and the analysis thereof, the understanding of pile test loading in current engineering practice leaves much to be desired. The reason for this is that the engineers have concerned themselves with mainly only one question: “Does the pile have a certain least capacity?”, finding little of practical value in analysing the actual capacity and the pile-soil interaction. This Paper aims to show that engineering value can be gained from elaborating on a pile test —during the actual testing in the field, as well as in the analysis of the results. T
he first portion of the notes make use of an earlier paper by the author (Fellenius, 1975) however, additional views and recent literature have been incorporated.
