Question

For designing end bearing piles of square cross-section in clays having average unconfined compressive strength of $6t/m^2$, the net ultimate bearing capacity may be taken as

• A. $15t/m^2$
• B. $18t/m^2$
• C. $20t/m^2$
• D. $27t/m^2$

Answer 1

The correct option is D $27t/m^2$

End bearing resistance,

$q_0=9c_u$

$c_u=\frac{6}{3}=3t/m^2$

$\therefore q_0=9\times 3=27t/m^2$
