What it calculates
OmniPile calculates axial capacity, group settlement, t-z/q-z load transfer and p-y lateral response for single and group piles.
- Shaft and toe resistance, representative capacity and utilization
- Group efficiency and group settlement
- Head load-settlement, layer t-z and toe q-w curves
- Lateral displacement, moment, shear and soil reaction with depth
Inputs
Pile geometry and design load are combined with soil or rock parameters required by the selected method.
- Layer depths and method-specific cu, φ, γ, qc, qu or RQD
- Section type, diameter or b×h, pile length and design load
- Group layout and design code/partial factors
- Groundwater level affects methods using effective stress
Outputs and reports
Results show capacity components, load-displacement curves and design checks together.
- Shaft/toe resistance, group factors and design resistance
- t-z/q-w curves and settlement at the design load
- p-y profiles, maximum-moment depth, head rotation and displacement
- Analysis summary, plots and report exports
Validation
OmniPile documentation describes analytical and published-table checks; it does not claim field validation for every method.
- For a uniform elastic soil p-y check, reported error is below 5% for a free head and below 6% for a fixed head.
- An independent axial-resistance check reports 34 fs/qb comparisons across 11 clay and 6 sand cases as PASS (<1e-9).
- Independent worked-example or field validation for group settlement is pending; heed warnings for missing method inputs.
Who it is for
OmniPile is intended for geotechnical and structural engineers designing pile foundations.
- Engineers checking single-pile and pile-group capacity
- Design teams reviewing load-transfer curves and lateral pile response
Frequently asked questions
Which soil parameter should I enter?
Required inputs depend on the selected method; for example, the alpha method needs cu, the beta method needs γ and φ, and the CPT method needs qc.
Does groundwater affect every method?
No. The guide says groundwater level affects only methods that use effective stress.
Can a result be produced when a method input is missing?
Some methods can use a default with a warning; such a result may not be data-driven from the entered soil information.
Has group settlement been checked against independent field data?
The current validation note lists independent worked-example or field validation as pending.
