Evaluation of the Vane Shear Test in Louisiana
An extensive review of literature on field testing indicated the vane shear test had the greatest potential for measuring in-situ properties of soft to medium clays prevalent in Louisiana. A Swedish Vane Borer was used at selected sites throughout the state. In-situ shear strengths measured by the vane shear test were compared with undrained shear strengths determined by laboratory unconfined and triaxial compression tests on samples taken by conventional tube sampling and on a few hand-carved samples. In-situ shear strengths as determined by the vane shear test were from 2.0 to 2.5 times the shear strengths from laboratory tests on tube samples and were more comparable to shear strengths of hand-carved samples. Miniature vane shear tests on tube samples indicated shear strengths more comparable to laboratory strengths. Sensitivity indicated by in-situ remolding with the vane was greater than sensitivity as determined by triaxial compression tests.
