Settlement of shallow foundations. Refer to the Environmental & Engineering Geoscience (Nov. 2012) study of methods for predicting settlement of shallow foundations on cohesive soll, Exercise 7.50 (p. 326). Actual settlement values for a sample of 13 structures built on a shallow foundation were determined, and these values compared to settlement predictions made using a formula that accounts for dimension, rigidity, and embedment depth of the foundation. The data (in millimeters) are reproduced in the table below. Use the SAS printout on the next page to test the hypothesis of no difference between the mean actual and mean predicted settlement values. Test using a.05.
