A retaining wall is shown below to support two layers of soil. fc' = 23 MPa and fy = 420 MPa. Use 28mm diameter bars for the transverse reinforcement and 12mm for the longitudinal reinforcement. 

 

The parameters per layer are given below:

  • Surcharge = qs = 8.04 kPa.
  • Layer 1: H1 = 1.96m. γ = 15.74 kN/m3. Φ = 21 degrees
  • Layer 2: H2 = 4.98m. Gs = 2.64. e = 0.44. S = 23.32%. Φ = 31 degrees.

What is the minimum wall thickness (mm)? 

 

Is |H1 = m Y = H2 = m 0 = E II||
Transcribed Image Text:Is |H1 = m Y = H2 = m 0 = E II||
