Definition. A wall for holding in place a mass of earth or the like, as at the edge of a terrace or excavation. A retaining wall is a structure designed and constructed to resist the lateral pressure of soil, when there is a desired change in ground elevation that exceeds the angle of repose of the soil.. A basement wall is thus one kind of retaining wall.

concrete structures. The focus would be on the corner joints (or connections) between structural members in the D-regions. Some typical corner joints often seen in practice include beam-column, joints, wall-base joints in retaining walls and liquid retaining structures, wing-walls of abutments etc. The behaviour of these

Retaining walls are as the name suggests any wall that is designed to retain any material. The material could be earth, water, anything else that needs to be retained. A common example of a retaining wall in everyday life is basement walls, swimming pool walls, and landscape walls.

Jun 01, 2020· Retaining structures are designed to resist the pressures of the retained materials, support loads imposed on the retained soil surface, and in some cases, support buildings or other structures. For instance, abutment walls can be used to provide support for bridges and traffic underpasses as well as to retain the ground at the approaches.
