Learning Objectives

  • Piles can be classified based on application, material type, and installation method.

  • End bearing and friction piles serve different purposes based on soil conditions and load transfer mechanisms.

  • Understanding the factors governing the selection of pile hammers is critical for effective pile driving.

Key Concepts

Piles

Vertical structural elements that transfer loads from buildings and structures to deeper, more stable soil layers.

End Bearing Pile

A type of pile that transfers load through the base of the pile to a hard bearing stratum.

Friction Pile

A type of pile that transfers load through friction between the sides of the pile and the surrounding soil.

Sheet Pile

A type of pile used to create barriers for earth and water, often utilized for retaining walls and cofferdams.

Timber Pile

The oldest type of pile made from timber that is known for its ease of use and lower cost.

Auger Boring

A method of creating holes in the ground using a rotating helical drill bit, commonly used for installing cast in place concrete piles.

Displacement Method

A pile installation method where the soil is displaced to make way for the pile, creating pore water pressure changes.

Non-Displacement Method

Installation approach that minimizes disturbance to surrounding soil during the pile installation.
