CPT Tool - Soil Behaviour Type
The CPT Tool is supplied with three soil behaviour type (SBT) interpretation methods:
- Robertson (1990)
- Robertson (1990) Extrapolated (axis extrapolated out)
- Schneider, Randolph, Mayne and Ramsey (2008)
- Robertson, Campanella, Gillespie and Greig (1986)
- Robertson, Campanella, Gillespie and Greig (1986) qc vs. Rf (applicable when u2 isn’t measured)
Additional methods may be defined by users.
The SBT can be summarised on to your existing borehole description lithology/stratigraphy table.
Your existing material graphic code can be associated with each SBT number,
geotechnically insignificant layers may be excluded, and thin layers of the same type
(fine/coarse) can be appended together.
