Technical Notes

Practical notes for slope stability modelling.

Technical explainers for geotechnical engineers reviewing slope stability models, checking assumptions, and interpreting the behaviour behind the calculated factor of safety.

Look beyond the headline result

Each technical note focuses on a practical modelling or interpretation issue that can help engineers review 2D and 3D limit equilibrium analyses more clearly.

  • Review modelling assumptions
  • Interpret internal force behaviour
  • Understand critical 3D mechanisms
  • Apply engineering judgement

Model Review and Analysis Checks in TSLOPE

Factor of safety is only one part of slope stability analysis. Review the failure mechanism, stress distribution, tension, weak layers, and differences between 2D and 3D behaviour.

  • Failure mechanism checks
  • Tension and stress distribution
  • Weak layer influence
  • 2D and 3D comparison
