Determine the allowable bearing capacity of a 10 m × 15 m mat foundation, placed at a depth of 3 m in sand (N_{60} = 27), which can accept 40 mm settlement.
From Eq. (12.43),
F_d =1+0.33(D_f/B)=1+0.33(3/10)=1.10
From Eq.(12.44b),
q_{net}=\frac{N_{60}}{0.08}\left(\frac{B+0.3}{B}\right)^2 F_d\left(\frac{S_e}{25}\right)=\frac{27}{0.08}\left(\frac{10+0.3}{10}\right)^2 (1.10)\left(\frac{40}{25}\right)=630 kN/m²
