For a retaining wall with specified layer properties where Ko = 1 - sin(φ) and γw = 10 kN/m3 (given sin 20° = 0.342), determine the lateral earth pressure at rest (Po) at points B and C:
- 1At point B, Po = 71.1 kN/m2 At point C, Po = 33.56 kN/m2
- 2At point B, Po = 33.56 kN/m2 At point C, Po = 71.1 kN/m2✓
- 3At point B, Po = 33.56 kN/m2 At point C, Po = 51.32 kN/m2
- 4At point B, Po = 51.32 kN/m2 At point C, Po = 33.56 kN/m2
Correct answer
At point B, Po = 33.56 kN/m2 At point C, Po = 71.1 kN/m2
