How to Use
- Select a geotechnical analysis module: bearing capacity (Terzaghi/Meyerhof), settlement (elastic/Schmertmann), consolidation (Terzaghi 1D), slope stability (Fellenius/Bishop), retaining wall (Rankine/Coulomb), pile capacity (static formulas), or liquefaction (SPT-based CRR).
- Input soil parameters: unit weight (γ), friction angle (φ), cohesion (c), elastic modulus (Es), permeability (k), and layer thickness.
- Apply loading conditions (foundation width B, depth Df, applied stress, groundwater table depth) and run simulation to generate bearing capacity factors, settlement curves, or safety factors.
Worked Example
For a shallow square foundation on medium dense sand: B=1.5 m, Df=1.0 m, γ=18.5 kN/m³, φ=32°, c=0 kPa. Meyerhof method yields Nc=35.5, Nq=23.2, Nγ=19.1, giving ultimate bearing capacity qu=520 kPa. With factor of safety 3.0, allowable bearing capacity qa=173 kPa. Settlement using Schmertmann method with Es=25 MPa over 2 m influence depth: immediate settlement ≈18 mm, primary consolidation ≈12 mm, total ≈30 mm.
Practical Notes
- For clay layers, run consolidation analysis using Cv from oedometer tests to predict settlement timescale; Terzaghi solution indicates time to 50% consolidation at typical H=5 m, Cv=5 m²/year is 2.5 years.
- Use Bishop's simplified slope stability method for circular failure surfaces when FS is marginal (1.0–1.5); compare with Fellenius for rapid validation.
- Liquefaction potential peaks when SPT N60<15 blows/foot in saturated silts near water table; CRR factor for magnitude 7.5 earthquake governs design depth in seismic zones.
- Retaining wall earth pressure at rest (K0=1-sinφ) applies to tied-back walls; active Rankine pressure (Ka) controls cantilever design; check base sliding friction coefficient ≥0.4 for dense sand.
