A 650-kN column load is supported on a 1.5 m wide by 2.0 m long by 0.5 m deep spread foot-
ing. The soil below is a well-graded, normally consolidated sand with g = 18.0 kN/m3
and the
following SPT N60 values:
Depth (m) 1.0 2.0 3.0 4.0 5.0
N60 12 13 13 8 22
The groundwater table is at a depth of 25 m. Compute settlement of the footing using the gen-
eralized elastic method with Christian and Carrier’s (1978) influence factors.
