The shallow foundation shown in Figure 3.19 measures 1.2m X 1.8 m and is subjected to a centric load and a moment. If and the depth of the foundation is 1 m, determine the allowable load the foundation can carry. Use a factor of safety of 3. For the soil, we are told that unit weight friction angle φ’ = 35°, and cohesion c’ = 0

Example 12.6 A square foundation is shown in Figure 12.9. Assume that the load eccentricity e 0.5 ft. Determine the ultimate load, Qut Sand y = 115 lb/ft d' = 30° 5ft X5ft c' 0 Figure 12.9

Q2: Compute the total stresses, which induced from geostatic stress and increase vertical stress from circular foundation under points A and B to 3 and 6 m depth from the base of the foundation. The foundation was constructed at 2.0 m below the natural ground level (NGL). The surface load intensity is 330 kN/m². R1= 4, (calculate R2 from the drawing, do not assume it). Assume any other parameter you need in your answer. Aqs net

4. A flexible foundation is shown below, determine the immediate settlement below the center of the foundation. Assume the thickness of the soil below the foundation is 20 meters. Following is the variation of the modulus of the soil below the foundation. Es (kN/m²) Depth below the foundation(m) 0-4 4-8 8-20 >20 1.2m 10000 8000 12000 ∞ 90 = BXL = 2m x 2m Us = 0.3 150kPa
