Home Assignment: Example 6.3A rectangular raft of size 30 x 12 m founded at a depth of2.5 m below the ground surface is subjected to a uniformpressure of 150 kPa. Assume the center of the area is theorigin of coordinates (0, 0). and the corners havecoordinates (6, 15).Calculate stresses at a depth of 20 m below the foundationlevel by the methods of (a) Boussinesq, and (b)Westergaard at coordinates of (0, 0), (0, 15), (6, 0) (6, 15) and (10, 25).Also determine the ratios of the stresses as obtained by thetwo methods. Neglect the effect of foundation depth on thestresses.13
