# Dataset Description

## Database
The database can be found as an attachment file, "Train.csv". For more information on the database refer to [(Stuyts et al., 2024)](https://www.mdpi.com/2673-7094/4/2/33). The provided data sets include the information on:

| Parameter | Definition | Type |
| --- | --- |
| Project | Project name or ID | Raw data |
| Testing spot | Location of the testing | Raw data |
| *Z* [m] | Depth | Raw data |
| *V<sub>s</sub>* [m/s] | Shear wave velocity (from seismic test) | Raw data |
| *q<sub>c</sub>*, *q<sub>t</sub>*, *f<sub>s</sub>*, *u<sub>2</sub>* [MPa] | Cone tip resistance, corrected cone tip resistance, sleeve friction, pore pressure | Raw data|
| *Q<sub>t</sub>* [-], *F<sub>r</sub>* [%], *B<sub>q</sub>* [-], *I<sub>c</sub>* [-] | CPTu-based soil behavior indicators | Interpreted |
| *σ<sub>v0</sub>* [kPa] | Vertical in-situ total stress | Interpreted |
| *σ'<sub>v0</sub>* [kPa] | Vertical in-situ effective stress | Interpreted |
| *e<sub>0</sub>* [-] | Void ratio (from CPTu) | Interpreted |
| *γ* [kN/m<sup>3</sup>] | Bulk unit weight (from CPTu)| Interpreted |

The interpretation equations are mentioned in the 'Appendix'. *Feel free to use your own interpreted values!*
