Unformatted text preview: the circular area (R) = 6 ft and that the uniformly distributed load (q) = 5000 lb/ft 2 , calculate the vertical stress increase (Δσ z ) at points 1.5, 3, 6, 9, and 12 ft below the ground surface (at the center of the circular area). 6. Figure 2 shows a flexible circular area of radius R = 4m. The uniformly distributed load on the circular area is 300 kN/m 2 . Calculate the vertical stress increase at r = 0, 0.5, 1.0, 1.5, 3.0, 6.0, and 12.0 m, and z = 5.0 m. Provide answers in a table format. 7. Use the pyramid method (2:1) to calculate Δσ v (KPa) at point A under the footing center and B outside the footprint in Fig. 3. 8. Use the Boussinesq method (“mn”) to calculate Δσ v (KPa) at point A under the footing center and B outside the footprint in Fig. 3. 9. Figure 4 shows an embankment load for a silty clay soil layer. Determine the vertical stress increase at points A, B, and C....
