#200. 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
#201. 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
#202. 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.
A 1.63
B 1.50
C 1.37
D 1.25
Answer: 1.25
