3.25 In a site consisting entirely of clays, an electric friction cone
penetrometer measures the cone resistance q, 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/m2, respectively.
Estimate the undrained shear strength, preconsolidation
pressure, and overconsolidation ratio at this depth.
