Every Curve.
On the Log.

Plot cone resistance, sleeve friction and pore pressure against depth together with corrected and derived values, and put them on the PDF log next to the layers.

  • ✓qc, fs, u2 and Rf against depth
  • ✓qt, σ'v0 and Fr
  • ✓Ic, N60 and moduli on the PDF

03 / INTERPRETATION

Layers from Ic.
Ready to Review.

Borebase splits the sounding into layers from the soil behaviour type index Ic and names them, with average qc, fs, Rf, Ic, N60, Su and M for each layer. Review them before they go on the log.

  • ✓Automatic layers from Ic
  • ✓Averages for every layer
  • ✓ISO 14688-1 soil names

Derived Values.
Open Formulas.

Corrected cone resistance qt, soil behaviour type, N60 equivalent, undrained shear strength Su and constrained modulus M are calculated for every point. The CPT methodology guide lists each formula.

  • ✓qt, Ic and soil behaviour type
  • ✓N60 equivalent and Su
  • ✓Moduli M and E
