Question

A plate load test was conducted by using a 60 cm square plate on the top of a sandy deposit, the ultimate bearing capacity was observed as $55kN/m^2.$ What will be the ultimate bearing capacity for a strip footing of 1.2 m width to be placed on the surface of the same soil?

• A. $79kN/m^2$
• B. $88kN/m^2$
• C. $110kN/m^2$
• D. $124kN/m^2$

Answer 1

The correct option is C $110kN/m^2$

For sandy soil
$(q_u{)}_f=(q_u{)}_p\times \frac{B_f}{B_p}$
$=55\times \frac{1.2}{0.6}$
$=110kN/m^2$
