Refer to the retaining wall described in Problem 15.8. If there is seepage in the backfill (as shown in Figure 15.8), what would be the magnitude of Pp based on the theory described in Section 15.7? Assume k_x = k_z and γ_sat = 18 kN/m³.

Data From Problem 15.8

Refer to Figure 15.22. Given: θ = 0, α = 0^ο, H = 5 m, γ = 15 kN/m³, ϕ' = 30^ο, and δ' =158. Estimate the passive force, P_p, per unit length of the wall using Caquot and Kerisel’s solution (Figure 15.6 and Table 15.6).
