## Question:

Redo Problem 12.30 assuming that the water table coincides with the top of the fill and that γ_{satsfilld} = 19.8 kN/m^{3}. If the other quantities remain the same, what would be the downward drag force on the pile? Assume δ' = 0.5ϕ'_{fill}.

**Problem 12.30**

Figure 12.49a shows a pile. Let L = 15 m, D (pile diameter) = 305 mm, H_{f} = 3 m, γ_{fill} = 17.5 kN/m^{3}, 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}.
