Abstract [en]

T-bar tests have become widely used for determination of undrained shear strength in foremost offshore investigations. Its use on land has so far been more limited. Apart from evaluation of the undrained shear strength from penetrations at a constant rate, evaluations of remoulded shear strength from cyclic pene-tration tests have also been performed. Cyclic tests can also be used to investigate how fast the shear strength is degraded with remoulding. For this purpose, T-bar tests have been performed in Swedish clays, as part of a larger project concerning the breakdown of shear strength at cyclic loading and deformations. The results have enabled a check of proposed methods for evaluation of undrained and remoulded shear strength with re-gard to Swedish clays, including highly sensitive and quick clays. The results indicate that the evaluation de-pends on several factors not taken into account earlier.
