Computes the maximum vertical stress exerted at the base of the wall using a uniform (Meyerhof) vertical stress distribution. This value is compared against the factored bearing resistance of the foundation soil. Internal Stability Calculations Step-by-Step Calculation Engine
Many spreadsheets include embedded charts to show pressure distributions and failure planes.
