In spite of the many recent advances in pile design and execution methods, the quantitive effects of pile installation method and form on subsequent pile behavior remain a research topic. This paper presents the results of static compression and tension tests on model piles (10 cm in diameter ad 1.5 m in length) in which soil type, installation method and pile shape were varied. The principal results of this study confirmed generally accepted trends. Separate shaft and toe measurements clearly showed the effects of installation method and pile taper on load transfer for a given soil type, while a comparison between these results and calculations according to classical pile bearing capacity methods brings to light certain shortcomings of current pile theory.
