Textbook Question
Chapter 12, Problem 12.31P
Redo Problem 12.30 assuming that the water table coincides with the top of the fill and that γsat(fill) = 19.8 kN/m3. If the other quantities remain the same, what would be the downward drag force on the pile? Assume δ' = 0.5ϕ′fill.
12.30 Figure 12.49a shows a pile. Let L = 15 m, D (pile diameter) 305 mm, Hf = 3 m, γfill = 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.
