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.
