Redo Problem 18.9 using the Hagerty and Nofal (1992) charts from Section 18.12.

Problem 18.9

Refer to Figure 18.23. Given L₁ = 3 m, L₂ = 6 m, l₁ = 1.5 m, γ = 16.5 kN/m³, γ_sat = 19.0 kN/m³, and ϕ' = 35°.

a. Find the required depth of the sheet pile, increasing the theoretical estimate by 30%.

b. Determine the force in the tie rods if they are spaced 3 m apart horizontally.

c. Find the maximum bending moment in the sheet pile.
