The next thing to consider is the assumptions that we can make in terms of the geometry of the retaining wall that we are designing. Approximate Proportions of a Cantilever Retaining Wall Refer to Figure A.2 below.įigure A.2-Retaining Wall Geometric VariablesĢ.
Unit Weight of Concrete, ɣ c: 25 kN/m 3.Worked Example:Ĭonsider the cantilever retaining wall with the cross-section shown in the above Figure A.1, which retains a 2m depth of soil having the groundwater table at -1.0m level. The purpose of this article is for the reader to fully understand the principle behind it.
This example is intended to be readily calculated by hand although a lot of structural spreadsheets and software such as Prokon are available. To further understand the designed approach, here is a worked example of the design of the retaining wall. We have learned the different checks against the mode of failures in the retaining wall should be considered in the design. Our previous article, Retaining Wall: A Design Approach discusses the principle and concept behind and when and where to consider a retaining wall in our design.
