A column footing of 1.8 mx 1.8 m is to be placed 1.5 m below ground level in a dry cohesionless soil. The unit weight of soil is 21 kN/m³ and angle of internal friction, $=36°. The footing is to carry total load 1350 KN including column load, weight of footing and weight of soil surcharge. Determine the factor of safety against bearing capacity failure assuming: (1) Ground water level well below the base of footing, and (ii) Ground water level at ground level Given for = 36°, N= 63.53, N=47.16, N₂=51.7 [Assume, Ybulk Ysaturated = 21 kN/m³] =
