Determine the allowable bearing capacity of the shallow foundation of size 5 ft x 5 ft as shown in Figure 3. Use Terzaghi's bearing capacity equation for the following groundwater conditions. Use Factor of safety (FOS) of 3.0. Dry unit weight of soil, y = 120 lb/ft, and Ysat = 125 lb/ft. (a) When water table ist10 ft below the ground surface (b) When water table 6 ft below the ground surface (c) When the water table is at the ground surface. The properties of the soil is given: = 35, c = 0 lb/ft. For = 35, Nc = 57.75, Nq = 41.44, Ny = 45.41. Square 5x5 ft 5 ft Figure 3 3 ft
