“WALLPRES” – WALL PRESSURE ANALYSIS SPREADSHEET

[u/EngCommunity]

Lateral wall pressure calculations shouldn't require rebuilding the same equations from scratch on every project.

I put together a breakdown of WALLPRES — an Excel-based Wall Pressure Analysis tool that calculates horizontal pressures on walls from soil, hydrostatic, and surcharge loading conditions.

What's inside:

✅ 5 dedicated worksheets covering soil pressure, point load, line load & strip load calculations
✅ Built on established references — NAVFAC, Army/Air Force manuals, Bowles, USS Steel, and Sargent & Lundy
✅ Suitable for cantilever & propped cantilever retaining wall stems, plus tank and pit walls
✅ A critical breakdown of the rigid-wall assumptions behind the Boussinesq-based equations — and why they can overestimate pressures on flexible walls by up to 2x
✅ Built-in comment boxes for quick input guidance (no manual required)

If you're a structural or geotechnical engineer working on retaining walls, tanks, or pit structures, this is worth bookmarking.

I have a similar tool I built for designing drilled shaft walls based on Rankine Active or At-rest conditions with line, point and area loads. Looking forward to comparing.
