Abstract

© 2015 Taylor & Francis Group, London. This paper investigates the effects of drainage on the performance of a sliding foundation as support to subsea pipeline infrastructure.A centrifuge test involving a sliding foundation on soft clay submitted to cycles of periodic monotonic undrained and drained sliding is presented.The results highlight the rise in sliding resistance under undrained conditions through cycles of sliding and intervening consolidation. The undrained resistance converges towards the drained value. Slow drained cycles encounter additional shearing resistance mobilised by ploughing of a drained soil berm ahead of the foundation.
