    • Abstract
  • The experiment on the plane creep of overconsolidated clay under cyclic loading is studied by using undisturbed samples. The results show that the consolidation deformation is the main characteristic of the normally consolidated and overconsolidated clay under static loading and plane creeping. The shear deformation is the main characteristic of the normally consolidated and overconsolidated clay under cyclic loading and plane creeping. The lateral deformation of the overconsolidated soft clay is less than that of the normally consolidated soft clay. The pore water pressure of saturated soft clay samples does not fluctuate at the initial stage of cyclic loading. The general trend is that the pore water pressure increases to the peak value and then decreases continuously, which is similar to the variation characteristics of pore water pressure under static loading. After cyclic loading for a long time, the pore pressure presents a fluctuating feature. The peak value of fluctuation decreases with time. The attenuation process is related to stress state and stress history.
