AB  - Chalk is present under large areas of NW Europe as a low-density, porous,weak carbonate rock. Large  numbers of offshore  wind  turbines,  bridgesand  port  facilities  rely  on  piles  driven  in  chalk. Current European practice assumesultimate shaft resistances that appear low in comparison with the Chalk’s unconfined compression strength and CPT cone resistance rangesand can impact very significantly on project economics. Little  guidance is available  on pile driveability, set-up or lateral  resistance in chalk, or on how piles driven in chalk can sustain axial or lateral cyclic loading. This paper describes the ALPACA (Axial-Lateral Pile Analysis for  Chalk  Applying  multi-scale  field  and  laboratory  testing) projectfunded  by  EPSRC  and  Industry that  is developingnew  design  guidance  through  comprehensive  field  testing  at awell-characterised  low-to-medium density  test  site, supported  by  analysis  of other tests. Field  experiments  on 36driven  piles, sixteen of which employ high resolution fibre-optic strain gauges, is supported by advanced laboratory and in-situ testing, as well as theoretical analysis. The field work commenced in October 2017 andwas largely complete inMay2019.
