Abstract : The results of consolidated-undrained direct-simple shear tests are presented on seven normally consolidated clays of widely varying composition and plasticity. The effect of overconsolidation ratio is studied with six of these clays. The tests were performed with the Geonor device, which uses a 8.0 cm dia. sample enclosed in a wire-reinforced rubber membrane. The vertical load is varied to maintain constant volume during undrained shear. Consolidated undrained direct-simple shear tests are easier to perform than K sub o - consolidated triaxial tests with pore pressure measurements. The test also yields data during consolidation similar to that obtained from conventional oedometer tests. (Modified author abstract)
