A group of total 16 piles are arranged in a square grid format. The center-to-center spacing (s) between adjacent piles is 3 m. The diameter (d) and length of embedment of each pile are 1 m and 20 m, respectively. The design capacity of each pile is 1000 kN in the vertical downward direction. The pile group efficiency (ηg) is given by
where m and n are number of rows and columns in the plan grid of pile arrangement, and θ=tan-1(d/s).
The design value of the pile group capacity (in kN) in the vertical downward direction is (round off to the nearest integer)
The design value of the pile group capacity (in kN) in the vertical downward direction is (round off to the nearest integer)
Correct : 11000
