Abstract

Unconfined compression tests have been widely used in Japan for the purpose of determining undrained strengths of clay samples, but the unconfined compressive strengths are usually scattered even if specimens tested seem to have been subjected to the same stress history. In order to make clear the cause of scattering of the measured strengths, a series of test simulating the process from sampling to unconfined and triaxial compression test for saturated clay samples was performed with a remolded clay and four undisturbed clays, and the influence of stress release and mechanical disturbance of test specimen on the undrained strength was examined. Based on the test results, a new method for predicting in situ undrained strength of clays from the results of conventional unconfined compression test with suction measurement was proposed.
