72 a) The ground water table is below the base of the wall, and the backfill soil is dry. Calculate the factor of safety of the wall against overturning and sliding. b) Assuming the water table rises up to the ground surface of the backfill during a rainstorm, recalculate the factor of safety of the wall against overturning and sliding.

Describe the role of each of the structural features circled in red of theretaining wall (arm or stem, heel, key and toe) depicted in Figure Q2(b)aimed at resisting the pressures/stresses being imposed on the retainingwall by the mass of soil, mass of the retaining wall and any moisturecontained in the soil. Make particular references to the actions of normalstresses, shear stresses and bending moments.
In retaining walls, what happen when lateral soil pressure exceeds the weight of the wall (its slab + its heel)? Hint: the wall cross section is ideal with toe and shear key. wall overtunes wall slides wall develops excessive bearing oressure
