The tie rods from anchored sheet piles will be connected using a row of anchors, as shown in Figure 18.46a. Here H = 2.0 m, h = 1.25 m, B = 1.5 m, S' = 2.5 m, ϕ' = 32°, and γ = 17.5 kN/m³. The anchor plates are made of 100 mm thick reinforced concrete with a unit weight of 24.0 kN/m³.

Determine the ultimate holding capacity of the anchor using Ovesen and Stromann’s method.
