100 p. Five cast in-situ Vibro piles were cast for the testing purpose with the load cells placed at the pile tip. They were 17, 20, 23 and 24 meters long, all piles have the same diameter of 52 cm. The cyclic pile loading tests were carried out after 28 and 66 days of pile casting. The 2 and % hour loading intervals were performed to every test pile. All piles failed at the settlement between 0.45 to 0.72 inch. There is no significant change of failure load with respect to the loading interval used. The shaft friction and the end bearing capacity of the pile were determined by load cells and by the graphical method proposed by JAIN and KUMAR, The result obtained from the graphical method was between 23 to 225 and 3 to 10 percent different from the load cell method for end bearing and shaft friction respectively. The adhesion constant (a) and the end bearing capacity factor (N) were computed from the results of the two methods. They were 0.49 to 0.89 and 3.94 to 14.22 based on the shearing strength obtained by vane shear and or standard penetration tests. For the results based on unconfined compression tests they were 1.03 to 1.37 and 4.69 to 15.50 respectively.
