Foundations and retaining structures.
Choose between shallow-foundation pressure or bearing-capacity screens and earth-pressure or retaining-wall stability checks. Ground conditions and geotechnical interpretation still govern the real design.

Choose the ground-structure check.
Inputs are simplified and do not replace a ground investigation, geotechnical model, settlement assessment, groundwater review, or project-specific safety basis.
Shallow foundations
Compare applied bearing pressure and estimate a simplified ultimate or allowable capacity.
- Shallow footing pressureAverage pressure and utilisation against a user-entered allowable value.
- Terzaghi bearing capacityPreliminary capacity factors, ultimate pressure, and factor-of-safety screen.
Earth pressure & retaining walls
Estimate active earth thrust and screen a simple gravity-wall load case.
- Rankine active earth pressureKa, soil and surcharge thrust, and overturning moment.
- Retaining-wall stabilitySliding, overturning, resultant location, and base-pressure screen.
Layering, groundwater, drainage, wall-soil interaction, seismic effects, settlement, global stability, construction sequence, and applicable Hong Kong or international geotechnical guidance require separate assessment.
