QUESTION 1
Using the ordinary method of slices, design the slope against sliding by using these
parameters:-
B = 45°, D'1 = 20°, O'2 = 25°,c' = 19.2 kN/m², Y = 18.08 kN/m³, y = 19 kN/m³,
Hj=3m, H2= 3m, a = 30°, 0 = 60°
Give comments with the number of slices that you choose.
QUESTION 2
Design this concrete retaining wall for Factor of Safety against overturning and sliding. Use
parameters at Question 1. Assume ground water table at 3m below soil surface, use 8 = 25 .
