A footing 6m square footing carries a total load. Including its own weight, of 10,000 kN. The base of the footing is at a depth of 3m below the ground surface. The soil strata at the site consists of a layer of stiff fully saturated clay 27.5m thick overlying dense sand. The average bulk density of the clay is 1,920 kg/m and its average shear strength determined from undrained triaxial test is 130 kPa. 44. Determine the gross foundation pressure. Use general shear failure table. A. 277.78 kPa B. 147.52 kPa C. 202.74 kPa D. 154.78 kPa 45. Determine the net foundation pressure. A. 63.52 kPa B. 199.52 kPa C. 221.26 kPa D. 200.54-kPa 46. Calculte the factor of safety of the foundation against complete shear failure under the undrained condition (both gross and net). Side cohesion on the foundation may be neglected.
