Introduction
Pile foundations are deep foundations formed
by long slender columnar elements.
They consist of two components:
Pile cap
single or group of piles.
Classification of pile foundations
Classified based on
load carrying characteristic of piles,
material of pile construction, and
type of soil.
End bearing piles(point bearing)
Friction piles
Classification based on load transmission
Timber piles
Steel piles
Concrete piles
Composite piles
Classification based on material of piles
construction:
Driven piles
Bored piles
Classification based on the effect of soil
Pile driving methods (displacement piles)
Dropping weight
Vibration
Jacking (only for micro piles)
Jetting
Pile Installation methods
Boring methods (non-displacement piles)
Continuous flight auger (CFA)
Underreaming
Contd…
Negative skin friction

Pile foundations are deep foundations consisting of long slender columnar elements, typically formed by a pile cap and single or group of piles. They are classified based on load-carrying characteristics, material of pile construction, and soil effects. Different installation methods include pile driving (displacement piles) and boring (non-displacement piles), with variations such as vibration, jacking, jetting, CFA, and underreaming. Understanding these classifications and installation techniques is crucial for civil engineers dealing with pile foundation projects.
