AB  - Driven piles are often employed to support onshore and offshore structures at low-density, porous weak carbonatechalk sites, which are encountered across Northern Europe and under the North and Baltic seas. Their efficient design is limitedby uncertainties regarding their ultimate axial capacity and load-displacement behaviour. Intensive axial testing has been under-taken recently for the ALPACA Joint Industry Project on piles driven at a UK chalk site, in conjunction with comprehensivechalk characterisation studies. This paper presents PLAXIS-2D numerical simulations of such piles' axial loading behaviour.The simulation accounts for three distinct zones of chalk identified around the pile shafts after installation. These comprise athin annular zone of de-structured, puttified, chalk and a second, thicker, annular zone of highly fractured chalk; both havedifferent mechanical properties compared to the surrounding parent intact chalk mass. The FE analyses investigate how shaftresistance, axial capacity and load-displacement behaviour develop differently in compression and tension tests.
