A 6 m. x 9 m. rectangular foundation carrying a uniform load of 288 kPa is applied to the ground surface. Compute the total vertical stress in kPa due to this uniform load at a depth of 6 m. below the center of the loaded area if unit weight of soil is 18,30 kN/m.

The 2 m x 4 m rectangular foundation is built 1.15 m below the ground surface and carries a total load, Q of 345 KPa (including column load, weight of concrete, and weight of backfill soil. The surrounding soil deposit has a unit weight of 20.68 kN/m³. Required Determine the total vertical pressure at a depth of 10 m below Point A. Provide answer in kN/m², to the nearest 100th. Your Answer:

A square shallow foundation has to carry a gross allowable total mass of 15,290 kg. The depth of the foundation is 0.7 m. The load is inclined at an angle of 20° to the vertical. The soil beneath and above the foundation is sand with effective friction angle of 30° and unit weight of 18 kN/m*. The ground water table is at a depth of 5 m below the bottom of the foundation. Determine the width of the foundation to achieve a factor of safety of 3.
