In a site consisting entirely of clays, an electric friction conepenetrometer measures the cone resistance qc at a depth of8.0 m as 0.75 MN/m2. The water table is at 3.0 m below theground level. The unit weights of the clay above and belowthe water table are 16.5 kN/m3 and 19.0 kN/m3, respectively.Estimate the undrained shear strength, preconsolidationpressure, and overconsolidation ratio at this depth.

Question
In a site consisting entirely of clays, an electric friction cone
penetrometer measures the cone resistance qc at a depth of
8.0 m as 0.75 MN/m2. The water table is at 3.0 m below the
ground level. The unit weights of the clay above and below
the water table are 16.5 kN/m3 and 19.0 kN/m3, respectively.
Estimate the undrained shear strength, preconsolidation
pressure, and overconsolidation ratio at this depth.
