A model-scale investigation into 'set-up' of displacement piles in sand
A model-scale investigation into 'set-up' of displacement piles in sand
A model scale investigation into set-up of displacement piles in sand is described. Thirty-two model piles were installed into two test chambers, and repeatedly load tested over a period of 100 days. Corrodible and inert piles were used, and in one test chamber the water table was cycled. Consistent profiles of penetration resistance and initial load test capacity confirmed the repeatability of the modelling procedure. Corrosion of the small model piles led to dramatic set-up. In the absence of corrosion, modest set-up was observed. Cycles of the water table significantly increased the amount of set-up, providing some suggestion of the governing mechanism, and indicating a possible technique for the enhancement of set-up.

Abstract
A model scale investigation into set-up of displacement piles in sand is described. Thirty-two model piles were installed into two test chambers, and repeatedly load tested over a period of 100 days. Corrodible and inert piles were used, and in one test chamber the water table was cycled. Consistent profiles of penetration resistance and initial load test capacity confirmed the repeatability of the modelling procedure. Corrosion of the small model piles led to dramatic set-up. In the absence of corrosion, modest set-up was observed. Cycles of the water table significantly increased the amount of set-up, providing some suggestion of the governing mechanism, and indicating a possible technique for the enhancement of set-up.
