Calculate Minimum Dimensions For Concrete Cantilever Retaining Wall Trial Design Section:
Use this calculation to come up with the minimum dimensions for the trial design section.  Then proceed with the design validation calculations.

Calculation:
Designer/Checker:

Input:

(Note: All input Metric units are converted to English units for the equations below and then the output English units are converted back to Metric)

Factor of safety against overturning (FS - typically 1.5 for granular soils and 2.0 for cohesive soils)
Height of retaining wall (H - ft or m)
Density of soil (d - pcf or kg/m^3)
Calculated overturning moment per unit length of wall (Ma - lb-ft/ft or N-m/m)

Resisting moment at heel, MR =
Required length of heel, HL =
Trial Width of Base, (based on backfill soil and wall height or proportioned as toe is 1/3 Heel Length), B =
Assume: Trial Base and Trial Stem Thickness = 12 in.
