Total pressure on the vertical face of a retaining wall of height per unit run exerted by the retained earth weighing per unit volume, is
A)wh [(1 - )/(1 + sin )]
B)wh² [(1 - )/(1 + sin )]
C)wh² [(1 - )/2(1 + sin )]
D)wh²[(1 - )/3(1 + sin )]

Question

Quizplus · Accepted Answer

The total pressure on the vertical face of a retaining wall is calculated using the formula for lateral earth pressure. The correct formula is wh² [(1 - sin φ)/2(1 + sin φ)], where w is the unit weight of the earth, h is the height of the wall, and φ is the angle of internal friction.
