For a smooth vertical wall supporting a granular backfill with ϕ' = 34°, determine Ka using Eq. (16.22) for α = 0, 5, 10, 15, and 20 degrees
Use Eq. (12.3), Figure P12.2, and the following values to determine the at-rest lateral earth force per unit length of the wall. Also find the location of the resultant. H = 5 m, H1 = 2 m, H2 = 3 m, γ = 15.5 kN/m3, γsat = 18.5 kN/m3, Φ' = 34º, c' = 0, q = 20 kN/m2, and OCR = 1.
For a smooth vertical wall retaining a granular backfill inclined at an angle of a = 15 ° , check whether Eqs . ( 16.70 ) and (16.72 ) ( or Tables 16.9 and 16.10 ) give the same values for the passive earth pressure coefficient . Use Ø' = 30° and 40°.
