AbstractPore pressure measurements at the base and within undisturbed specimens of a sensitive clay during consolidation and shear indicate that membrane leakage is not serious for ordinary tests. A technique for measuring pressures within the specimen is described. In the soil tested, greater pore pressures were developed at the lower end of the specimen than in the center and this was attributed to end restraint. Because failure occurs near the bottom of the specimens, the pressure measured at the base plate is considered to be satisfactory for the computation of effective stresses at failure.
