Pile Design and Construction Practice, Fifth edition

Maximum load on pile 3156 kN. If shaft friction on pile is fully developed, the
end-bearing load is 3156– 2465 691 kN, and thus

End-bearing pressure

Ultimate unit base resistance

From equation 4.36, with K 0.01,

Therefore individual piles will not settle excessively and the critical factor is the overall
settlement of the complete pile group, for which a movement of 50 to 100 mm over a long
period of years is by no means excessive.
