| The Undrained creep tests on the normally consolidated clays with four different consolication ratios(c3c'/clc': 1.0, 0.7, 0.5, 0.4) were performed to investigate the effects of avisotropic consolidation on the undrained creep rupture behavior. The elapsed time to a certain minimum strain rate is decreased with decreasing the value of the consolidation pressure ratio, and the elapsed time to rupture for a certain minimum strain rate is also decreased with decreasing the ratio. The upper yield strength obtained from the equation suggested by Finn and Shead(1.) is coincided well with the creep strength irrespective of the magnitude of the consolidation pressure ratio, and the normallised upper yielding strength by mean confining pressure is decreased with increasing the consolidation pressure ratio. The critical strain for creep rupture, the strain at min. strain rate, is constant irrespective of the magnitude of creep stress, but it increased exponentially with increasing the ratio, It accordingly is dangerous that the potential of in-situ creep rupture is estimated only by the creep rupture test on the isotropically consolidated clay in case of K0-value below 1.0. |
