CHARACTERISTICS OF QUASI-OVERCONSOLIDATED CLAY INDUCED BY CYCLIC LOADING

Abstract

The clay subjected to cyclic shear with drainage is in the state of quasi-overconsolidation. In order to investigate the characteristics of shear strength and of consolidation of quasi-overconsolidated clay, static shear tests and consolidation tests were carried out, using the simple shear test apparatus. Then, the results were compared with the ones for the overconsolidated clay. As a conclusion, it was clarified that quasi-overconsolidated clay induced by cyclic loading is affected with the disturbances of fabrics, comparing with the overconsolidated clay induced under static conditions.
