Question

As per Terzaghi's equation, the bearing capacity of strip footing resting on cohesive soil $(c=10kN/m^2)$ for unit depth and unit width $\left(assume{N}_{c}as5.7\right)$ is

• A. $47kN/m^2$
• B. $57kN/m^2$
• C. $67kN/m^2$
• D. $77kN/m^2$

Answer 1

The correct option is B $57kN/m^2$

(b)Bearing capacity

$q_{ult}=c{N}_c+q{N}_q+\frac{\gamma B}{2}{N}_{\gamma }$

For cohesive soil,

$N_q=1.0and{N}_{\gamma }=0$

$\therefore q_{net,ult}=q_{ult}-q$

$=c{N}_c=10\times 5.7$

$=57kN/m^2$
