![A square footing has a dimension of 1.30m. Its bottom is 1.5m below the ground surface. The
groundwater table is expected to exist during the life of the structure. The unit weight of soil above the
water table is 17.20 kN/m³ and that below the water table is 19.60 kN/m3 (saturated). 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
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
