Q1: Back fill with a sloping surface exerts a total active pressure Pa on the wall of height H and acts atA
H/4 above the base parallel to base
B
H/2 above the base parallel to base
C
H/3 above the base parallel to base
D
H/5 above the base parallel to base.
ANS:C - H/3 above the base parallel to base Same for passive case but valid in cohesion-less soil only. As pressure distribution is triangular, effective pressure acts at 1/3rd of total height from base. |
