The figure shows the soil profile at point 'A. The soil is the same above and under the water table. A building will be constructed on the top of the soil given in sketch 1, which will apply an additional pressure of 6,458-psf, find the consolidation of the clay strata in the sketch. The soil is over-consolidated, and the pre-consolidation pressure is 2,000 lb/sf Assume: Cc = 0.009*(LL - 10) Cs=0.10*Cc Cv=0.005469 in^2/min Density of water, gw = 62.4 lb/ft^3 Density of strata 1 = 108.0 lb/ft^3 Density of strata 2 = 121.0 lb/ft^3 Density of strata 3= 125.6 lb/ft^3 Liquid Limit, LL of strata 3:0.43 Initial void ratio for strata 3, 0.70 What is the time to obtain 90% of consolidation?
