3 The plan of a group pile is shown in Figure P11.23. Assume that the piles are embedded in a saturated homogeneous clay having a c, = 86 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. Use FS = 3.
