The feature and limitation of displacement piling

September 25,2023

Displacement piling, also known as displacement piles or driven piles, is a technique used in foundation construction to support structures and transfer their loads to deeper, more stable soil or rock layers. The key characteristic of displacement piling is that it involves driving a pile into the ground without removing soil or excavating the area. Instead, the pile displaces or pushes aside the soil as it is inserted. This method is in contrast to bored piles or drilled shafts, where soil is excavated to create space for the pile.

Features of displacement piling

Displacement piling is efficient and can be used in various soil conditions, including cohesive soils and loose sands.

It allows for quick installation, reducing construction time.

There is minimal excavation, which can be beneficial in environmentally sensitive areas or congested urban settings.

Limitations of displacement piling

The technique may not be suitable for extremely hard or rocky ground conditions.

Vibrations generated during pile driving can be a concern in densely populated areas or near sensitive structures.
