Question

Compute the increase in vertical stress beneath the center of the foundation (i.e., relative to the
stresses that existed prior to construction) at depths of 0 ft, 3 ft, 9 ft, and 15 ft beneath the base
of the footing (i.e., at depths of 2 ft, 5 ft, 11 ft, and 17 ft beneath the ground surface).



2a. Determine the increase in vertical stress (psf) at a depth of 0 ft beneath the footing.
2b. Determine the increase in vertical stress (psf) at a depth of 3 ft beneath the footing.
2c. Determine the increase in vertical stress (psf) at a depth of 9 ft beneath the footing.
2d. Determine the increase in vertical stress (psf) at a depth of 15 ft beneath the footing.
