Refer to Figure 7.10. For the retaining wall, and c′ = 0.

a. Determine the intensity of the Rankine active force at z = 2 m, 4 m, and 6 m.

b. Determine the Rankine active force per meter length of the wall and also the location and direction of the resultant.

Figure 7.10

Use Eq. (7.3), Figure P7.2, and the following values to determine the at-rest lateral earth force per unit length of the wall. Also find the location of the resultant. H = 5 m, H₁ = 2 m, H₂ = 3 m, γ = 15.5 γ_sat = 18.5 φ ′ = 34°, c ′ = 0, q =20 and OCR = 1.
