Using two sets of analytical solutions for CPTU in clays, a suite of theoretically-consistent geoparameters is shown to be in good agreement with independent laboratory and field test results obtained on sensitive Presumpscot clay in Portland, Maine, USA. Fall cone tests indicate a mean sensitivity of St ≈ 37. Values of undrained rigidity index (IR ), undrained shear strength (su ), and yield stress ratio (YSR) are provided by a modified spherical cavity expansion-critical state hybrid model while an effective stress limit plasticity solution is utilized to assess the effective friction angle of the sensitive clay at both peak strength [ϕ' at qmax ] and also at maximum obliquity [ϕ' at (σ1 '/σ3 ')max ]. A CPTU screening method that uses three simplified equations for YSR helps to identify that the clay is sensitive.
