Definition of Gravity Retaining Wall Chegg

Retaining wall is employed to bear the soil mass or backfill on the back side of the wall. There are four types of retaining wall available as follows, 1) Gravity wall, 2) cantilever wall and 3) anchored wall. In these types, the gravity wall uses self-weight to counter the forces coming from retained soil mass.
