A rectangular footing 3m by 4m is founded 1.2m below the ground surface for which the unit weight of soil is 17.8kN/m3. The cohesion strength is 10kPa and the angle of internal friction is 20degrees. Under the condition of general failure, evaluate the contribution from 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 factor. For Ø=20degrees: Nc = 17.69, Nq = 7.44, Ny = 3.64. 23. Due to Cohesion Strength Due to soil overburden Due to footing dimension

Question
A rectangular footing 3m by 4m is founded 1.2m below the ground surface for which the unit weight of soil is 17.8kN/m3. The cohesion strength is 10kPa and the angle of internal friction is 20degrees.
Under the condition of general failure, evaluate the contribution from 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 factor. For Ø=20degrees: Nc = 17.69, Nq = 7.44, Ny = 3.64. 23.
