A field investigation into the mechanisms of pile ageing in sand

The design of axially loaded piles has been an area focus for the offshore industry in recent years. A number studies report substantial increases shaft capacity driven sand, known as pile ageing. slow to implement ageing into practice because uncertainty over mechanisms controlling and variability on impact This paper presents results tests using instrumented with two separate installations considered, one where was load tested 4 days after installation second test performed period 116 days. Data from installation, period, testing extraction provide further insights governing effect time axial sand.
