Civil Engineering MCQAE Level Civil Engineering
A slope is to be constructed at 30° to the horizontal in a soil with C = 15 kN/m², φ = 22.5°, γ = 19 kN/m³. Taylor's stability number is 0.046. For a factor of safety (with respect to cohesion) of 1.5, the safe height of the slope will be

Choose the correct answer
A
25.8 m
B
19.1 m
C
17.2 m
D
11.5 m
Correct Answer
D. 11.5 m
Why is this the answer?
H = c/(Sn F gamma) = 15/(0.046x1.5x19)=11.5 m.
