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 maybe 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).
