Pile spacing and Types
The center to center distance of successive piles is known as pile spacing.It has to be carefully designed by considering the following factors,
Types of piles
Material of piles
Length of piles
Grouping of piles
Load coming on piles
Obstruction during pile driving
Nature of soil through which piles are passing.
Types of pile
Load bearing piles
Non-load bearing piles
Load bearing piles :-
It bear the load coming from the structure.
The Piles are generally driven vertically or in near vertical position.
When a horizontal forces to be resisted, the inclined piles may be driven in an inclined position and such inclined piles are termed the batter piles
Load bearing piles are divided into,
The spacing between piles in a group can be assumed based on the following:
1- Friction piles need higher spacing than bearing piles.
2- Minimum spacing (S) between piles is 2.5.
3- Maximum spacing (S) between piles is 8.0.
