The plan of a group pile is shown in the figure. Assume that the piles are embedded in a saturated homogeneous clay having a cu=90 kN/m2 . Given: Diameter of piles (D)=316 mm, center-to-center spacing of piles=600 mm, and length of piles= 20 m. Find the allowable load-carrying capacity of the pile group. Using FS=3 and table.
