its problem 17.6 on foundation engineering ninth edition by Braja M.Das 17.6 ung Coulomb's earth pressures. It is required to design a cantilever retaining wall to retain a 5.0 m high sandy backfill. The consultant suggests the dimensions and soil properties shown in Figure P17.6 and requires that the wall be checked for stability with respect to sliding and overturning based on the active earth pressures determined using 0.5 mm 110° EDT Sand y = 18.5 kN/m3 6' = 36°...
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.
