Question

46. A cylindrical concrete pile with a diameter of 8 in. and a length of 10 ft. is to be used to support a foundation in clay soil. Calculate the end bearing (EB) and skin friction (SF) for this pile. Assume c = 25 kPa, Nc = 9, and α = 1.

a. EB = 33.56 kN, SF = 7.545 kN b. EB = 3.27 kip, SF = 7.439 kip c. EB = 1.11 kip, SF = 8.65 kip d. EB = 7.30 kN, SF = 48.64 kN

47. Assume you have the same volume of concrete the was used for the pile in the previous

problem to pour another cylindrical pile. What is the total bearing capacity if the new pile has a diameter of 10 in.?

a. 28.29 kip b. 125.85 kN c. 11.47 kip d. 91.65 kN
