Estimating the end bearing resistance of pipe piles in sand using the final filling ratio
Abstract
Recent research has highlighted the effect of the soil core development during pile installation, on the axial resistance developed during static loading of driven pipe piles in sand. This paper summarises the experimental findings from recently conducted field tests designed to investigate the factors controlling the development of base resistance of pipe piles. These provide the framework for a new design method which incorporates a direct measure of soil core development into the calculation of base resistance. A database of pile load tests on large scale pipe piles has been assembled, which enables features of full-scale pile behaviour to be identified as well as facilitating a review of current design methods.
