ABSTRACT
Existing methods for predicting pile axial capacity are relatively unreliable. This paper illustrates the vital role that research involving static load testing can play in improving deep foundation design, describing an extended study undertaken by a group from Imperial College into the axial capacity of driven pipe piles. A precis is given of the main features of the new design procedures which have been developed from the work. The latter are shown to offer considerable theoretical and practical advantages over existing calculation procedures.
