Part of: Sedimentation Consolidation Models—Predictions and Validation


Three kinds of clay with different plasticity were pre-consolidated from slurry and combined into typical two layered systems consolidated under 40 tf/m**2 with single drainage condition. Three specimens of each type were consolidated until the degree of consolidation reached 40, 80 and 100 percent, respectively, to obtain isochrones at each degree of consolidation. The time-consolidation curves and isochrones are compared with numerical solutions using Mikasa's equation.
