Question
(e) A soil profile consists of a clay layer between layers of sand, the water table being in the
upper sand layer. Before the construction of a raft foundation for a large reservoir, piezometers were placed in the saturated clay layer. The whole process of filling the reservoir may be approximated to applying rapidly a single pressure increment of 200 kPa uniformly throughout the clay layer. One year after filling the reservoir, the piezometers indicated a distribution of excess porewater pressure as indicated in Figure Q-e. Estimate the average degree of consolidation at this time.
