PRINCIPLES OF FOUNDATION DESIGN
Terzhagi's Ultimate Bearing Capacity 5. A long footing 2 m wide is buried at a depth of 1 m. The groundwater table is expected to exist during the life of the structure. Soil above the water table has a unit weight of 19.65 kN/m3 and the saturated soil has a unit weight of 21.70 kN/m3. Angle of internal friction is 20 degrees and cohesion is 15 kPa. Using general shear failure and a factor of safety of 3.0. Calculate the following: 25pts a. Gross allowable bearing capacity if the water table is 4m from the ground surface b. Gross allowable bearing capacity if the water table is 2m from the ground surface c. Gross allowable bearing capacity if the water table is at the embedment of the foundation d. Gross allowable bearing capacity if the water table is 0.5 m from the ground surface
