A cantilevered retaining wall was originally designed with a base width of 3 m but it was
actually constructed with a base width of 1.8 m. The original design incorporated a factor of safety of
2 and ignored passive pressure. Compute the total lateral force acting on the wall.
A
154.29 kN
B
187.66 kN
C
221.78 kN
D
124.33 kN
Answer: 124.33 kN

A cantilevered retaining wall was originally designed with a base width of 3 m but it was
actually constructed with a base width of 1.8 m. The original design incorporated a factor of safety of
2 and ignored passive pressure. Compute the location of the resultant lateral force from the bottom of the wall footing.
A
1.47 m
B
2.13 m
C
1.96 m
D
1.77 m
Answer: 1.77 m

A cantilevered retaining wall was originally designed with a base width of 3 m but it was
actually constructed with a base width of 1.8 m. The original design incorporated a factor of safety of
2 and ignored passive pressure. Compute the new factor of safety against overturning moment about the toe.
