Nine piles of 300 mm dia and 8 m length are arranged in a square pattern for the foundation for a column in a uniform deposit of medium stiff clay (qu the centre to centre spacing of piles is = 100 kN/m2). If 900 mm and adhesion factor = 0.9, calculate the capacity of the pile group assuming a F.O.S. of 2.5.

Solve correctly
Nine piles of 300 mm dia and 8 m
length are arranged in a square
pattern for the foundation for a
column in a uniform deposit of
medium stiff clay (qu = 100 kN/m2). If
the centre to centre spacing of piles is
900 mm and adhesion factor = 0.9,
calculate the capacity of the pile group
assuming a F.O.S. of 2.5.
