Tests on Model Jacked Piles in Calcareous Sand



This paper presents the results of a series of displacement-controlled cyclic axial loading tests of model jacked piles in dry calcareous sand. The tests were conducted using a large test facility comprising a test chamber 1.0 m in internal diameter and 1.55 m in height. Model instrumented aluminum jacked piles 50 and 100 mm in diameter were used to investigate scale effects on the degradation of skin friction capacity under cyclic loading conditions. Test results are presented for the response during jacking (installation), initial static compression loading, cyclic loading, and post-cyclic static compression loading response. It is shown that the degradation of skin friction is governed by the “cyclic slip displacement” model.
