SPO — Simple Pile One¶
Version 1.0.1 · Windows 64-bit
A complete platform for pile analysis, design and detailing, covering the main pile construction methods used in Brazil.
Project limits¶
The ceiling of 200 piles in total is the one that matters in practice: a hundred caps of thirty piles would be three thousand, and that is not what the program supports. The limits act together, and whichever is reached first governs.
Pile types¶
| Bored with slurry | Continuous flight auger (CFA) | Precast |
| Bored without slurry | Omega | Franki |
| Root pile |
What it does¶
-
Bearing capacity
Three semi-empirical methods side by side — Aoki-Velloso, Décourt-Quaresma and Teixeira — with results by level.
-
Settlement
Cintra & Aoki, group settlement and the Van der Veen load × settlement curve.
-
Structural design
Biaxial bending with axial force of a circular section with interaction diagram, and shear by the truss model.
-
Reinforcement detailing
Interactive detailing and DXF export.
-
Report
Interactive, editable calculation report in DOCX.
-
Soil-structure interaction
Winkler springs and finite element structural analysis.
Documentation¶
SPO is the core of the SP line: SPX is SPO with two extra features, and SPX AI is SPX with AI automation. All three share the same calculation engine.
That is why the documentation is not written three times — it would be three copies to keep in sync, and the first divergence between them would be a design error waiting to happen. The SPX manual and formulations apply in full to SPO in the common modules, which are almost all of them.
-
Interface, pile cap setup, borehole, geotechnical results, structural analysis, design, detailing and report.
-
Bearing capacity, settlement, soil reaction, structural analysis, design and parameter tables.
-
The two SPX features that SPO does not have, and what to do without them.
-
The bibliography, shared by all three.
Difference from SPX¶
SPO does not have:
- Raked pile analysis — individual rake and azimuth.
- Stratigraphic profile modelling — interpolation between boreholes and 3D profile.
- Editable reader for borehole PDFs.
