Earth retaining structure

Earth retaining structure is a working sheet for retaining wall sections. Enter the geometry, the backfill and the water; get the active thrust, the resultant height, three factors of safety and a pressure profile you can read at a glance. Real soil mechanics, not a black box. Earth retaining structure computes Rankine and Coulomb active and passive coefficients, integrates layered backfill with effective stress, adds pore pressure separately so a water table is never silently underestimated, and handles sloping fill and uniform surcharges. Mononobe-Okabe pseudo-static seismic thrust is one slider away. A trial-wedge search double-checks the closed-form result — if the two disagree, the app tells you the section is outside the model rather than hiding it. The whole section, three verdicts. Wall weight and stabilising moments are computed from the true geometry of gravity, cantilever,…
