Displacement Piles in Sand - Time Evolution of Pile Shaft Resistance


The phenomenon of pile set-up (i.e. increase in pile shaft resistance with time) in sand has been reported for decades but the observations are widely scattered and mechanisms leading to this increase are poorly understood. An investigation is initiated by performing careful experimental research using instrumented reduced-scale field piles conducted at several sand sites of different mineralogy and groundwater regimes. In addition, a laboratory-scale model test is designed to further study the influence of a variety of parameters on pile set-up. The results, combined with observations from well-selected case histories, are examined to explain the myth of this ageing phenomenon.

Why my research is important

The capacity gain with time, if successfully justified with greater understanding on its governing mechanisms, permits a major cost benefits for foundation construction. It is also of great interest for reuse of existing foundations, which is now a major consideration in many urban redevelopments around the world.
