Study of soil responses adjacent to jack-up spudcan foundation

Abstract

Centrifuge model tests have been conducted to investigate the soil responses during penetration, jack-up rig operation and extraction of a jack-up spudcan foundation in soft clay. The penetration and extraction process of a half-cut spudcan were captured by a digital camera at 100g. Image processing technique involving Particle Image Velocimetry was then applied to evaluate the induced soil movements in the adjacent field of the moving spudcan. The development of pore pressures adjacent to the spudcan was also monitored. Copyright © 2010 by ASME.
