Question: Figure 12.49a shows a pile. Let L = 15 m, D (pile diameter) = 305 mm, H f = 3 m, fill = 17.5

Figure 12.49a shows a pile. Let L = 15 m, D (pile diameter) = 305 mm, H_f = 3 m, γ_fill = 17.5 kN/m³, and ϕ'_fill = 25°.

Determine the total downward drag force on the pile. Assume that the fill is located above the water table and that δ' = 0.5ϕ'_fill.
