ocedures invol by-step procedures suggested PROBLEMS 7.1 A 7.5 ft wide rough continuous foundation is placed in the ground at 3.0 ft depth. There is bedrock present at 3 ft depth below the bottom of the foundation. The soil properties are c' 210 lb/ft², 6' = 25°, and y = 12 7.3 74 7.5 = 115.0 lb/ft³. Determine the ultimate bearing capacity of the foundation. In Problem 7.1, if there was no bedrock present for at least 12.0 ft below the foundation, what would the ultimate bear- ing capacity be? A 1.5 m x 2.0 m rectangular foundation is placed at 1.0 m depth in sand where ' = 40° and y = 18.5 kN/m³. Bedrock is present at 1.0 m below the foundation. Using Eq. (7.3), determine the ultimate bearing capacity of the foundation. In Problem 7.3, if no bedrock was present for at least 4 m below the foundation, determine the ultimate bearing capacity. A 2.0 m wide square foundation is placed at 0.5 m depth in a saturated clay where c₁ = 40 kN/m² and y = 19.0 kN/m². == There is a very stiff stratum present at 1.0 m below the foundation. Determine the ultimate bearing capacity using Buisman's (1940) equation. 7.6 A 2.0 m wide continuous foundation is placed at 1.5 m depth in a saturated clay where c₁ = 40 kN/m² and y = 18.5 kN/m². At 2.0 m below the ground level, this clay layer is underlain by a stiffer clay where cu = 60 kN/m² and y = 19.0 kN/m³. What would be the maximum wall load allowed with FS = 32 Use Eq. (7.11). q.8.0.101.v2A 1.7 Redo Problem 7.6 using Vesic's (1975) solution [Eq. (7.12)]. 78 A2 m wide continuous foundation is placed at 1 m depth Wish 7.11 7.12 7.12 7. dorlain by a weaker 7.
