An earth embankment is shown in Figure 10.44. Determine the stress increase at point A due to the embankment load. Given: β = 25°, γ = 119 lb/ft 3, x = 55 ft, y = 28 ft, and z = 20 ft.
For the embankment shown in Figure 10.45, determine the vertical stress increases at points A, B, and C
An embankment consists of clay fill for which c=25 kPa and angle of internal friction is 260 (from consolidated undrained test with pore pressure measurement) The weight of fill per unit volume is 18.64 kN/m3. Compute the effective stress in kPa at a depth of 20 m. If the pore pressure at this point is shown by a piezometer to be 180 kPa.
