A square footing of 4 m. side is placed at 1 m depth in a sand deposit. The dry unit weight (γ) of sand is 15 kN/m3. This footing has an ultimate bearing capacity of 600 kPa. Consider the depth factor; dq=dγ=1.0 and the bearing capacity factor : Nγ=18.75 . This footing is placed at a depth of 2 m in the same soil deposit. For a factor of safety of 3.0 for Terzaghi's theory, the safe bearing capacity (in kPa) of this footing would be270

1.	A square footing of 4 m. side is placed at 1 m depth in a sand deposit. The dry unit weight (γ) of sand is 15 kN/m3. This footing has an ultimate bearing capacity of 600 kPa. Consider the depth factor; dq=dγ=1.0 and the bearing capacity factor : Nγ=18.75 . This footing is placed at a depth of 2 m in the same soil deposit. For a factor of safety of 3.0 for Terzaghi's theory, the safe bearing capacity (in kPa) of this footing would be270
Answer» A square footing of 4 m. side is placed at 1 m depth in a sand deposit. The dry unit weight ( $γ$ ) of sand is 15 kN/ $m^{3}$ . This footing has an ultimate bearing capacity of 600 kPa. Consider the depth factor; $d_{q} = d_{γ} = 1.0$ and the bearing capacity factor : $N_{γ} = 18.75$ . This footing is placed at a depth of 2 m in the same soil deposit. For a factor of safety of 3.0 for Terzaghi's theory, the safe bearing capacity (in kPa) of this footing would be 270
