Example 7. 10 A strata of normally consolidated clay of thickness 10ft is drained on one side only. It has a hydraulic conductivity of k = 1.863 x 10-s in/sec and a coefficient of volume compressibility m

v = 8.6 x 10-4 in2/lb. Determine the ultimate value of the compression of the stratum by assuming

a uniformly distributed load of 5250 lb/ft2 and also determine the time required for 20 percent and 80 percent consolidation.
