Abstract: This paper describes field studies concerning the behavior of drilled piers under axial loading and presents preliminary design procedures. The drilled piers were instrumented for measurement of axial load as a function of length and data were obtained on load transfer along the sides of the piers and in point bearing. Correlations were made between soil properties and load transfer for a number of field tests. Preliminary design procedures, based on the analyses of the experiments, are suggested.
