Figure Q2 depicts a concrete retaining wall described as T-shaped concrete, cast insitu in stiff undrained clay and supporting Gravelly SAND. The front of the wall has the same soil. 0.30m Gravelly SAND H=3m 1.0m 0.50m 1.00m 0.30m Stiff (undrained) Clay Figure Q2 An original ground water level is 2m below the backfill surface, and due to adequate drainage system installed behind the wall the potential for the water level to rise to the surface is considered unrealistic. However, a safety margin approach is adopted where the water level is increased to 1m below the backfill level. Assuming suitable material parameters consistent with the given description of both the ground and the backfill verify the ULS for overturning and sliding using the EC7 DA1:C2.

Figure Q2
An original ground water level is 2m below the backfill
surface, and due to adequate drainage system installed
behind the wall the potential for the water level to rise to
the surface is considered unrealistic. However, a safety
margin approach is adopted where the water level is
increased to 1m below the backfill level.
Assuming suitable material parameters consistent with
the given description of both the ground and the backfill
verify the ULS for overturning and sliding using the EC7
DA1:C2.
