A water tank foundation has a footing of size 6 x 6 m founded at a depth of 3 m below ground level
in a medium dense sand stratum of great depth. The corrected average SPT value obtained from the
site investigation is 20. The foundation is subjected to a vertical load at an eccentricity of B/10
along one of the axes. Figure Ex. 12.15 gives the soil profile with the remaining data. Estimate the
ultimate load, Quir by Meyerhof's method.
