A simple visual schematic or chart showing the wall profile, reinforcement layers, and length configurations. Step-by-Step Mathematical Workflow for the Spreadsheet
The spreadsheet has been validated against:
This involves checking for global slope failure. A traditional slope stability analysis (e.g., using the Bishop method) ensures that a deep-seated failure surface does not pass through or below the wall, causing a catastrophic collapse of the entire structure.
: Unlike commercial software where calculations happen behind the scenes, spreadsheets display every formula explicitly. Reviewing engineers and agencies can click on cells to trace exactly how a safety factor was derived.
These are typically developed by private companies for sale, offering robust features, customer support, and regular updates.
Total and differential settlement of the wall is estimated using classical consolidation or elastic settlement theory, depending on the foundation soil type. The spreadsheet may also compute lateral wall deflection (serviceability check) to ensure it remains within acceptable limits.
This article provides a comprehensive overview of utilizing an for geotechnical and structural design, based on standard engineering practices.
: Federal Highway Administration (FHWA) manuals and associated spreadsheets, such as the FHWA-RD-89-193 method
As a starting point for the design, the spreadsheet suggests a preliminary reinforcement length, typically ( L \ge 0.7H ) for most applications, although project-specific requirements or local standards may prescribe a different minimum. The designer inputs this length and proceeds to the stability analyses.
If you are currently setting up a sheet or checking a project, let me know:
– Horizontal force equilibrium at the base of the reinforced zone. Spreadsheets calculate driving force (active earth pressure + surcharge) and resisting force (friction along base + passive resistance if present). Target FS ≥ 1.5 (LRFD: φ factor ~0.9).
Check each reinforcement layer from top to bottom. If a layer fails tensile overstress, reduce the vertical spacing or swap in a higher-strength geogrid. If it fails pullout, increase the total length ( Step 5: Export the Design Report
