Transcribed Image Text:A square footing 4 m. on a side is founded 1.2 m below the ground
surface for which the bulk unit weight of the soil is 20 kN/m3, the
cohesion strength is 10 kPa and the angle of internal friction is 20
degrees. Under the condition of general failure, evaluate the contribution
of the following to the ultimate soil bearing capacity in kPa. The ground
water table is at a level that does not affect the unit weight of the soil.
Use Terzaghi's bearing capacity factors.
