Abstract

Foundation piles of offshore wind farms and other engineering structures, including dolphins as well as anchor piles of floating offshore facilities, are predominantly laterally loaded. Near the pile head the lateral response is weak and compliant owing to the low soil strength and stress level close to the seabed. The lateral bearing capacity can be improved by enlarging the pile near the pile head by adding 'wings'. This cross-sectional expansion increases the overall resistance from the soil, with the added benefit of enabling a reduction in required pile length. This paper presents experimental results from laterally loaded piles in sand with and without enlargement at the pile head and compares the observed behaviour. The tests were conducted in the beam centrifuge at the University of Western Australia.
