Dam Stability Analyzer — Ebora

🏔️ Dam Stability Analyzer

Check a concrete gravity dam (trapezoidal section, vertical upstream face) about the toe: self-weight & centroids, headwater thrust, tailwater, and a trapezoidal uplift on the base. Returns the factors of safety against overturning and sliding, the resultant eccentricity (middle-third / no-tension), and the base pressures — with a force diagram and PDF.

Worked solution

⚠️ Idealized 2-D gravity-dam check per metre length (vertical u/s face, trapezoidal uplift). Earthquake, ice, silt, wave and 3-D effects are not included. Use typical minimum FoS ≈ 1.5 (sliding) and 1.5–2 (overturning) — verify against your design code and professor's load combinations.
