What is pile foundation design?

The design of pile foundation involves providing adequate pile type, size, depth, and number to support the superstructure load without excessive settlement and bearing capacity failure. The resistance to the applied structural load is derived mainly from the frictional resistance developed at the soil–pile interface.

How are pile foundations constructed?

The pile casing is typically driven into earth or the ground and filled with concrete and reinforcement to arrive at the cast-in-situ pile. The other method involves an auger that is hollow stemmed that drills into the ground. This auger is then pumped with a material such as concrete in order to build up the pile.

What are the types of pile foundation?

5 Types of Pile Foundation

• Bored Piling.
• Driven Piling.
• Screw Piling.
• Mini Piling.
• Sheet Piling.

What is the minimum depth of pile foundation?

Depth of deep foundation depend on applied load on structure If the load on foundation is 500KN, minimum depth is 3.5m to 4.5m, If the load on foundation is in the range of 2000KN to 3000KN, minimum depth for pile foundation is 6.0m to 20.0m with pile caps.

What is the purpose of a pile foundation?

The main purpose of a pile foundation is to transfer the loads into a strong stratum . 2. Generally, pile foundations are used when the bearing capacity of soil is very low and the structural load is heavy.

What is a pile foundation in civil engineering?

Pile, in building construction, a postlike foundation member used from prehistoric times. In modern civil engineering, piles of timber, steel, or concrete are driven into the ground to support a structure; bridge piers may be supported on groups of large-diameter piles.

What is the definition of a pile foundation?

Pile foundation, a kind of deep foundation, is actually a slender column or long cylinder made of materials such as concrete or steel which are used to support the structure and transfer the load at desired depth either by end bearing or skin friction. Pile foundations are deep foundations.

What is pile grouping in pile foundation?

What is Pile Grouping in Pile Foundation? Pile is a deep foundation. This is a way to transfer loads from superstructure through the pile, developing frictional capacity and end bearing, to firm stratum. This is obvious, that a single pile cannot always enough to bear the loads from column to be supported.
