The resultant active pressure per unit length of wall for dry backfill with no surcharge acting at _________ above the base of wall.

The resultant active pressure per unit length of wall for dry backfill with no surcharge acting at _________ above the base of wall. Correct Answer H/3

The pressure distribution of the stresses in the retaining wall due to the backfill is triangular one. Since the pressure distribution is triangular, the resultant active pressure per unit length of wall will act at the centroid of the wall, which is at a distance of H/3 from the base of the wall.
