This document discusses the design of a cantilever retaining wall. It defines the key parts of a retaining wall, including the base slab, stem, toe, and heel. The base slab constitutes the footing that the wall rests on. The stem is the wall itself, with the front face being exposed and the back face against the backfill. The toe and heel are portions of the base slab that extend beyond the front and back faces of the wall, respectively. It provides references for further information on cantilever retaining wall design and comparisons between cantilever and counterfort walls.
