CPT Tool - Dissipation Test

CPT Tool

The most user-definable Cone Penetration Testing software available.

Log and SBT graph

Work without limits as you define which types of soil data to present in log, fence, cross-section and graph reports.

  • Define correlation formulas and reports
  • 200+ Preconfigured correlations and derivations
  • 600+ customisable log, fence/cross-section and graph reports

CPT Tool places advanced reporting directly in the hands of geotechnical engineers with code-free report definition and an array of formula configurations, analysis and report options unmatched in cone penetration testing.

Speed up soil data interpretation with rich-data visualisation in any situation, adapting reporting output to changing requirements and conditions across projects.

CPT Tool - Dissipation Test

Dissipation tests may be analysed using the strain path method (SPM) proposed by Houlsby and Teh 1988. Further, dissipation tests carried out in over consolidated soils may be corrected using the square root time method as proposed in Sully et al. 1999, and short tests may be extrapolated forward to estimate tx, (e.g. t50).
