Question

The plate load test was conducted on a clayey strata by using a plate of $0.3m\times 0.3m$ dimensions, and the ultimate load per unit area for the plate was found to be 180 kPa. The ultimate bearing capacity (in kPa) of a 2m wide square footing would be

• A.
  27
• B.
  180
• C.
  1200
• D.
  2000

Answer 1

The correct option is B

180
Bearing capacity of footing on purely cohesive soil does not depend upon size of footing.

$q_{up}=q_{uf}\left(forclay\right)$

$\therefore$ Ultimate bearing capacity of a 2m wide square footing = 180 kPa
