During an Oedometer test, a thick soil sample completed of consolidation for 5 minutes. Calculate the time for consolidation for a 10 m thick layer (drainage is allowed only at the top) of the same clay:
Expert Answer
To calculate the time for consolidation for a 10 m thick layer of the same clay, we can use the concept of time factor or time ratio in consolidation. The time ratio is defined as the time required for a given percentage of consolidation in a certain thickness compared to the time required for the same percentage of consolidation in a reference thickness.In this case, the reference thickness is 10 mm, and we know that it took 5 minutes to achieve 50% consolidation for this thickness. We want to find the time required for 50% consolidation for a 10 m (10,000 mm) thick layer.
