Question

The load carrying capacity of an individual friction pile is \(200\) kN. What is the total load carrying capacity of a group of \(9\) such piles with the group efficiency factor of \(0.8\)?

• A. \(1800\) kN
• B. \(1640\) kN
• C. \(1440\) kN
• D. \(900\) kN

Hint:

For pile groups, \[ \boxed{ Q_g=\eta nQ_p } \] If the group efficiency is less than \(1\), the pile group capacity is less than the sum of the individual pile capacities.

Answer 1

The Correct Option is C
