Problem 1 (33 points) The plan of a group pile is shown below. The three piles form an equilateral triangle. The piles are embedded in a saturated homogenous clay with \( C_{u}=1,500 \) psf. The diameter of each pile is 1 foot. The center-to-center distance between the piles is 3 feet. Length of each pile is 60 feet. Using a factor of safety of 4, determine the allowable load-carrying capacity of the pile group. Use factor safety of 4 . Length of each pile is 60 feet.
