+ Analysis of Retaining Walls
SIT X. A vertical retaining wall 6 m high retains a horizontal backfill having the following
properties: void ratio = 0.60, specific gravity = 2.60, water content = 24% and angle
of internal friction = 25°.
a. Compute the magnitude of the active force acting on the wall if the water table is
on the ground surface which is on level with top of the wall.
b. Compute the magnitude of the active force acting on the wall if the water table is
lowered at a depth of 3 m from the ground surface.
c. Compute the magnitude of the active force acting on the wall if the water table is
at the bottom of the wall.
