A retaining wall refers to a structure designed and built to combat with the lateral pressure of soil once a desired alteration occurs in ground elevation that surpasses the angle of repose of the soil.
The active pressure enhances on the retaining wall in proportionate ratios from zero at the higher grade level to a highest value at the lowest depth of the wall. In order to become functional, retaining walls should be reinforced properly.
Civil Engineering Retaining Wall Design Spreadsheet can be useful to design a retaining wall through an easy to follow process. The spreadsheet consists of tabs to work out stability, moment and shear, reinforcement etc.
