A unit volume of a mass of saturated soil is subjected to horizontal seepage. The saturated unit weight is 22 kN/m3 and the hydraulic gradient is 0.3. The resultant body force on the soil mass is
-
- 1.98 kN
- 6.6 kN
- 11.49 kN
- 22.97 kN
Correct Option: D
Seepage pressure per unit volume = i = γw
= 0.3 × 9.81 = 2.94 3 kN
Total vertical force = (2.2 kN/m2) × vol = 22 kN
∴ Resultant = √222 + 2.9432
= 22.19 kN
