A 2.0 m wide continuous foundation is placed at 1.5 m depth in a saturated clay where cu=40kN/m^2 and y=18.5 kN/m^3. At 2.0 m below ground level, this clay is underlain by a stiffer clay where cu=60 kN/m^2 and y=19kN/m^3. What would be the maximum wall load allowed with FS=3

Problem 3: (45 points) A square foundation was decided to be constructed to support the load of a column in a residential building construction project located in Claremont, CA. During the site investigation, only sandy soil (c'=0) was encountered. The ground water was observed at the depth 1.2m from ground level. Obtained samples were tested in the lab and the internal friction angle of the soil was found to be equal to 30°. The unit weight of the soil above...
