displacement pile

displacement pile

A solid pile or hollow pile whose lower end is closed so that in being driven, the pile displaces an equivalent soil volume (either by compaction or soil displacement).

The displacement pile is the oldest type of deep foundation and due to its proven efficiency is acknowledged and often employed in geotechnical engineering practice.
Although a lot of theories, methods and techniques were developed to predict and simulate the behaviour of displacement pile in cohesion-less soil (Baziar et al.

Chan and Hanna [4] showed that the cyclic response of displacement piles in sand is affected by the number of cycles, their frequency, the mean shaft load, the shaft cyclic load amplitude, the pile depth, the loading history, and the properties of the surrounding sand.
