PROBLEM NO. 1 (50 POINTS): A pile group consists of 12 piles with a diameter of 0.3 m and a pile length of 12 m is driven into the clay soil layers with details below: Depth (m) Soil Test Result 0.00 -4.00 m y = 18.18 +0.1(last digit of your ID number) kN/m3 CU = 58+ 0.1(last digit of your ID number) kPa 4.00 - 9.00 m y = 18.18 +0.1(second to the last digit of your ID number) kN/m3 Cu = 76 +0.1(second to the last digit of your ID number) kPa 9.00 - 12.00 m r = 18.18 + 0.1(third to the last digit of your ID number) kN/m3 Cu = 95 + 0.1(third to the last digit of your ID number) kPa The piles are spaced in 3 piles by 4 piles rectangular configuration with a pile spacing of 0.60 + 0.01 (last digit of your ID number) m center to center of piles. Determine the allowable load on the pile. The following are the considerations in determining the allowable load: a. Use alpha and beta method. b. Consider that the piles are acting individually. C. Consider that the piles are acting as a group. d. Use the usual constants of Nc and Nq. e. Use F.S. = 3.0
