QUESTION 4 A reinforced cantilever retaining wall supports a granular soil as shown in the following diagram. The unit weight of concrete is 23.5 kN/m3 and the interface friction between the base of the wall and the soil is equal to the angle of shearing resistance ø of the retained soil. Ignoring any passive resistance from the soil in front of the wall check whether the wall complies with Eurocode 7 Design Approach 1 regarding GEO limit state for overturning and sliding.
