The spreadsheet should automatically calculate and verify the following factors of safety (FoS) or resistance factors: Check Type What it Measures Target/Method External: Sliding Ability to resist lateral earth pressure. Factor of Safety typically is greater than or equal to 1.5 External: Bearing Capacity of foundation soil to support wall weight. Pressure < Allowable Bearing Capacity. External: Overturning Eccentricity of the resultant force. Resultant must stay within the middle third of the base. Internal: Pullout Resistance of reinforcement to being pulled out of soil. Check at each reinforcement layer. Internal: Tensile Strength of the reinforcement material itself. Actual stress < Long Term Design Strength ( cap L cap T cap D cap S 4.

Every time the wall height changes by six inches, the engineer has to re-calculate the active earth pressure coefficients ( Kacap K sub a But the real story is what happened next

Once the template is built, you can perform "what-if" analyses—such as changing the geogrid length or reinforcement type —to find the most cost-effective design in seconds.
Even seasoned engineers make mistakes. Integrate these checks into your design spreadsheet:
Ensuring the reinforcement has enough strength to withstand the calculated tensile forces.
: Years later, when a heavy truck route is proposed for the road above the wall, engineers pull up the original spreadsheet to see if the soil quality and wall width can handle the new loads.
