Piles and a diaphragm wall of a supported berthing structure on marine soils are loaded
both axially and laterally. Axial loads are typically generated by the self weight of the
structure and external live loads; lateral loads are typically generated by wave current
and seismic loads. These loads are generally considered in the design of berthing
structures. However, the lateral force generated by lateral soil movements due to
dredging may not be considered or accounted in the design of berthing structures.
Hence, a full-scale field study was conducted on a berthing structure to estimate the
actual axial load distribution during axial loading and the lateral displacement during
dredging. After construction of the berth, it was decided to conduct a full scale axial load
test on a single pile and monitor the lateral movements of the berth during and after
dredging. This paper describes the load transfer data obtained from a bored cast – in –
situ pile socketed 1.5 m into hard rock and the lateral displacement of the berth recorded
during and after dredging to a -9.5 m dredge depth.
