A Versatile Control System for Triaxial Testing of Soils



Specimens of sedimented kaolinite were subjected to consolidated-undrained triaxial compression by means of a new electropneumatic control system that will apply any desired loading path in the axisymmetric stress space or any desired deformation path. Specimens were tested under ramp loading, ramp deformation and combined ramp loading—ramp deformation with both constant cell pressure and constant first invariant of the applied stress tensor. To determine the entire stress-strain-pore pressure relationship, it was necessary to perform the combined load rate-deformation rate test. It was found that while a unique principal stress difference-major principal strain relationship exists, a unique pore pressure-major principal strain relationship does not exist.
