Following are basic steps to designing a retaining wall. Download our guides for complete details with design examples.
1. Establish project requirements including all geometry and external loads.
2. Evaluate site subsurface conditions and determine relevant soil properties.
3. Determine load acting on wall including lateral earth pressure distribution plus any external loads (surcharges).
4. Perform engineering analysis to determine required embedment depth (and unit anchor rod tension, if anchored wall) so that the resulting load and reactions satisfy the conditions of static equilibrium.
5. If anchored wall, design anchor system size and spacing and structural top cap with capacity to handle the unit anchor pull.
6. Calculate maximum bending moment acting on the wall and select a concrete reinforcing design whose factored moment capacity exceeds the maximum moment. Factored moment capacities are tabulated in the Truline design manual.
