Figure2.4.a: Bearing capacity failure for retaining wall Failure principles for retaining walls are similar to those for embankment when bearing capacity of the foundation is insufficient to carry the load pf soil block and facing wall failure will occur. • Sliding out at the base Sliding failure will occur when the friction between the reinforced soil and sub grade is low and the retaining wall can simply slid side way. Figure2.4.b: Sliding failure. • Overturning Overturning is the most common failure mode for retaining wall. The horizontal earth pressures behind wall exceed the capacity of geogrid to restrain. The wall will rotate forward pivoting on its base. Figure2.4.c: Overturning failure. • Using anchor in retaining wall will help to reduce the thickness of reinforcement by introducing the anchor which can provide with a good passive resistance. Figure 2.4.d: Anchor used to provide passive
