WebProblem 7.6: Cantilever Wall. Check the stability of the cantilever wall of the figure below. Given: unit weight of soil: γt=1.70 T/m3, angle of internal friction: φ =40°, angle of friction between wall base and soil: φB=30°. unit weight of concrete: γ=2.35 Τ/m3. Solution. Web• For the Coulomb case shown above with no soil-wall friction (i.e. δ = 0) and a horizontal backfill surface, both the Coulomb and Rankine methods yield equal results. • As the soil friction angle (φ) increases (i.e. soil becomes stronger), the active pressure coefficient decreases, resulting in a decrease in the active force while the Webis an empirical coefficient related to the soil's corn- pressibility and degree of saturation. For saturated soils, B = 1. For an elastic material, A = 1/3. For soils that compress under shear, A > 1/3, and for soils that dilate under shear, A < 1/3 Under the fully drained condition, the excess pore pressure is zero, and pore pressure in satu- plantain oil uses
