Scholarcy highlights

  • Laboratory experiments on undisturbed specimens of a large number of soft clay deposits, as well as previous measurements on clays and granular soils, were used to examine and explain the magnitude and behavior of the coefficient of earth pressure at rest, K0: after sedimentation – primary consolidation, during secondary-compression aging, after active or passive preshearing away from the laterally constrained condition, during a decrease in effective vertical stress, and during an increase in effective vertical stress in the recompression or compression range, in terms of, the slope of the effective horizontal versus effective vertical stress path
