Question: A 3.05-meter-thick clay layer is drained at the top and bottom. Its characteristics are c vr = c v (for vertical drainage) = 39.02 cm

A 3.05-meter-thick clay layer is drained at the top and bottom. Its characteristics are c_vr = c_v (for vertical drainage) = 39.02 cm²/day, r_w = 203 mm, and de 51.83 m. Estimate the degree of consolidation of the clay layer caused by the combination of vertical and radial drainage at t = 0.2, 0.4, 0.8, and 1 year. Assume that the surcharge is applied instantaneously, and there is no smear.
