The piles developed very high shaft resistance and, in contrast to piles driven into boulder clay which exhibit friction fatigue, the shaft distribution was uniform along the pile shaft. This resulted in the normalised average shear resistance being mobilised by a bored pile exceeding that of a pile driven in similar ground conditions. In contrast the base resistance of the test piles were significantly lower than a pile driven in similar ground conditions.271454 bytesapplication/pdfenField testing and monitoringFoundationsGeotechnical engineeringPilesPilingFoundations--TestingPiling (Civil engineering)Engineering geologyJournal Article161417118010.1680/geng.2008.161.4.171https://creativecommons.org/licenses/by-nc-sa/1.0/
