A buried clay layer ten feet thick is sandwiched between strata free draining granular soil so that double drainage during consolidation can occur calculations indicate that due to a planned building loading, an ultimate settlement of 2 inches is expected as a result of compression in the clay layer. The coefficient of consolidation for the clay layer is 0.01 ft.2/day. a) How long will it take for 90 % of the estimated settlement to take place ? b) How much settlement, H, will occur in one year %? c) How long will it take for an inch of settlement to take place ?
