3-The time for 75% consolidation of a 1-in clay specimen (drained at top and bottom) in the laboratory is 22 minutes. How long will it take for a 20-ft thick clay layer in the field to undergo 55% consolidation under the same pressure increment? In the field, there is a rock layer at the bottom of the clay,
2-Consider the soil profile shown below. Given: Ao=930 psf, H2=4.5 ft, H =9 ft, and Hy=16 ft. Soil characteristics are: Sand: Ya=112 pcf; Y=123 pcf Clay: You = 119 pcf;C=0.324; C=C/5 Estimate the primary consolidation settlement of the clay if: a. The clay is normally consolidated b. The preconsolidation pressure, c'#2,100 psf LU GWT eo=0.71 н Sand Clay
