Extraction of jackup spudcan foundations

Abstract

Centrifuge model tests were carried out to simulate the installation, operation, and extraction of a jackup spudcan foundation in normally consolidated clay. The uplift resistance during spudcan extraction was examined with particular attention paid to the development of suction at the spudcan base. The test results revealed that the suction developed at the interface between the spudcan base and the underlying soil can be the major resistance during extraction of spudcans with a relatively long operation period. © 2005 Taylor & Francis Group.
