... to analyse the dramatic variations in the states of stress and strain associated with displacement pile installation, employing parameters calibrated to triaxial test data on Fontainebleau test sand. The implemented PFEM and modified Mohr-Coulomb model approach is applied to simulate well-documented...

... ABSTRACT: Significant uncertainty exists regarding the effect of axial cyclic loading and installation technique on the ageing characteristics of displacement piles. To address this, the current study investigates the influence of installation method, pile shape and cyclic loading...

... tests at Dunkirk and elsewhere. The key contribution has been the measuring of the stress state evolution: (i) on the surface of a displacement pile; and (ii) in the surrounding sand mass. A range of cyclic loading pa- rameters under well controlled environmental condi- tions are taken...

... September 2007, London, UK 369 3. Correlations between Shaft Friction and CPT Cone Tip Resistance The insertion of a displacement pile or penetrometer in the ground causes an increase in the radial stress in the area near the pile tip, which is often correlated to CPT tip resistance, qc. The shaft friction...
