Chapter 16, Problem 16.5P
A square column foundation has to carry a gross allowable load of 1805 kN (FS = 3). Given: Df = 1.5 m, γ = 15.9 kN/m3,
The applied load on a shallow square foundation makes an angle of 15° with the vertical. Given: B = 1.83 m, Df = 0.91 m, γ = 18.08 kN/m3,

It is required to design a cantilever retaining wall to retain a 5.0 m high sandy backfill. The dimensions of the cantilever wall are shown in Figure 15.52 along with the soil properties. Check the stability with respect to sliding and overturning, based on the active earth pressures determined, usinga. Coulomb's earth pressure theory (δ' = 24°), andb. Rankine's earth pressure theory.The unit weight of concrete is 24 .0 kN/m3
The excavation 3 × 6 m for a foundation is to be made to a depth of 2.5 m below ground level in a soil of bulkunit weight = 20 kN/m3.What effect this excavation will have on the vertical pressure at a depth of 6 m measuredfrom the ground surface vertically below the centre of foundation? The influence factor for m = 0.43 and n = 0.86 is 0.10.
A 4.5m square foundation exerts uniform pressure of 200kn/m^2 on a soil . Determine
