Question:

Redo Problem 11.6 using the weighted average method [Eq. (11.68)] to calculate the stress increase in the clay layer.
In problem 11.6
Refer to Figure 11.43. Considering the soil to be a uniform clay layer, estimate the primary consolidation settlement due to the foundation load. Given: P = 150 kN; B = 3 m; L = 3 m; Df = 1.5 m; H = 8 m; e = 0.7; Gs = 2.72; and LL = 42. Assume that the clay is normally consolidated, and the groundwater table is at the foundation level. Use
