Figure 15.45 shows a gravity retaining wall retaining a granular (c' = 0) backfill. The same soil is present at the bottom of the wall and on the left. The unit weight and the friction angle of the backfill are 18.5 kN/m3 and 35°, respectively. The unit w
Figure 15.45 shows a gravity retaining wall retaining a granular (c' = 0) backfill. The same soil is present at the bottom of the wall and on the left. The unit weight and the friction angle of the backfill are 18.5 kN/m3 and 35°, respectively. The unit weight of concrete is 24.0 kN/m3. Determine the factors of safety with respect to overturning, sliding, and bearing capacity failure. Use Rankine earth pressure theory.

Figure shows a cantilever sheet-pile wall penetrating a granular soil. Assume, γ = 15.5 kN/m3, γsat = 18 kN/m3, φ΄ = 18o, and γw = 10 kN/m3.(a) Draw the pressure diagram of the cantilever sheet-pile wall (may not necessarily be on scale).(b) Determine the theoretical depth of embedment.(c) What should be the minimum section modulus of the sheet piles? Use σall = 180 MN/m2.
