Question
Determine the stability of the cantilever gravity retaining wall shown in figure below.
The existing soil is a clay and the backfill is a coarse-grained soil. The base of the wall
will rest on a 50-mm-thick, compacted layer of the backfill. The interface friction between
the base and the compacted layer of backfill is 25.0°. Groundwater level is 8 m below the
base.
