Question:

Refer to the Environmental & Engineering Geoscience (Nov. 2012) study of methods for predicting settlement of shallow foundations on cohesive soil, Exercise 7.50. 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 α = .05.


Data from Exercise 7.50

Structures built on a shallow foundation (e.g., a concrete slab-on-grade foundation) are susceptible to settlement. Consequently, accurate settlement prediction is essential in the design of the foundation. Several methods for predicting settlement of shallow foundations on cohesive soil were com-pared in Environmental & Engineering Geoscience (Nov., 2012). Settlement data for a sample of 13 structures built on a shallow foundation were collected. (These structures included office buildings, bridge piers, and concrete test plates.) The actual settlement values (measured in millimeters) for each structure were compared to settlement predictions made using a formula that accounts for dimension, rigidity, and embedment depth of the foundation.
