A normally consolidated clay layer is 3 m thick (one-way drainage). From the application of a given pressure, the total anticipated primary consolidation settlement will be 80 mm. a. What is the average degree of consolidation for the clay layer when the settlement is 25 mm? b. If the average value of c, for the pressure range is 0.002 cm?/s, how long will it take for 50% settlement to occur? c. How long will it take for 50% consolidation to occur if the clay layer is drained at both top and bottom? A normally consolidated clay layer is 3 m thick (one-way drainage).
