Question

A 10.0 ft x 6.25 ft rigid foundation rests on a granular soil deposit at D = 2.5ft, and carries a vertical load of 187,500 lbs. Bedrock is at a depth of 32 ft below the foundation Soil data are E, 32 ksi, Poisson's Ratio - 030,7 = 128 pcf, G, 265,= 33°, c = 0, C 25, C, - 72, and %-#200 - 4.2%. The anticipated elastic settlement of the foundation is most nearly
