Problem 5: A vertical retaining wall 5.0 m in height is supporting a horizontal backfill. The water table is located 2 m below the top of the wall. The unit weight of soil above the water table on level with the top of the wall is 16 kN/m3, and an angle of internal friction of 30º. The saturated unit weight of soil below the water table is 19 kN/m3, and an angle of internal friction of 30°. a) Find the lateral force at rest if it carries a horizontal (uniform) surcharge of 12 kN/m² on top of the level of the wall. b) Compute the location of the lateral force from the bottom of the wall. c) Compute the moment due to the lateral force.

Transcribed Image Text:Problem 5:
A vertical retaining wall 5.0 m in height is supporting a
horizontal backfill. The water table is located 2 m below
the top of the wall. The unit weight of soil above the water
table on level with the top of the wall is 16 kN/m³, and an
angle of internal friction of 30°. The saturated unit weight
of soil below the water table is 19 kN/m³, and an angle of
internal friction of 30°.
a) Find the lateral force at rest if it carries a horizontal
(uniform) surcharge of 12 kN/m² on top of the level of
the wall.
b) Compute the location of the lateral force from the
bottom of the wall.
c) Compute the moment due to the lateral force.
