Popis: |
Three series of consolidated undrained triaxial compression tests on two saturated remoulded clays were performed to investigate the influence of duration of anisotropic consolidation up to 120 days on the undrained stress-strain behavior of clays. Experimental results show that the initial modulus of deformation and the undrained strength increase with time of consolidation, and the increase in elapsed time of anisotropic consolidation leads to increase the stress level which exerts positive dilatancy at initial stage of shear. A method to predict the undrained shear strength of clay consolidated over a long period of time by applying existing method which has been applied to overconsolidated clay is presented. It is also shown that the method of prediction can be improved by suitable evaluation of the change in dilatancy characteristics of clay with the elapsed time in secondary consolidation. |
