Chapter 8, Problem 8.2QPP

A 250-k column load is to be supported on a 9 ft square footing embedded 2 ft below the ground surface. The underlying soil is a silty sand with an average $N_{60}$ of 32 and a unit weight of $129{\text{lb/ft}}^{\text{3}}.$ The groundwater table is at a depth of 35 ft. Estimate the undrained settlement of the footing using the generalized elastic method with Christian and Carrier’s (1978) influence factors.
