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 section of masonry dam is shown in Fig. U. If the uplift pressure variesuniformly from full hydrostatic at the heel to full hydrostatic at the toe, but acts only 2/3 of the area of the base,
find: (a) the location of the resultant, (b) factor safety against overturning, (c) factor of safety against sliding if the coefficient of friction between base and foundation is 0.60.
In the figure shown, the concrete dam is 16m high and 13m wide at the base. If the specific weight of the concrete is 23.544KN/m^3 and height of water in the upstream side is 15m, find the factor of safety against sliding, factor of safety against overturning, and the unit pressure on the foundation. Assume there is a hydrostatic uplift that varies uniformly from full hydrostatic head at the heel of the dam to zero at the toe and that the coefficient of friction between the dam and the foundation is 0.50.
