Abstract

The design of rigid retaining wall (Cantilever, Counterfort, Buttress) is based on pressure exerted by the retaining material, wall slope, height, ease of construction and stability. When the retaining wall height is more than 8 m, the selection of extra supports, i.e., either counterforts or buttresses is based upon the designer's experience. By conducting comparative study on resisting forces for varying heights, the behavior of these supports on retaining wall can be depicted. The depiction of forces can be achieved by running an analysis in STAAD.Pro with preliminary dimensions and soil parameters respectively. Resisting forces from counterfort and buttress supports on retaining wall are equal when the height is in between 9 m to 24 m but buttress support has shown less resisting forces when the height is less than 9 m.
