Abstract :
The Komering Cempaka East Oku Regency water bridge construction project uses a concrete pile group foundation, this type of foundation is capable of supporting a considerable burden. Therefore, this study focuses the study by comparing the efficiency of existing pile piles and variations of pile variations, to determine the carrying capacity of pile foundations based on N-SPT data using the vesic method (the Allpile Software). The exact research at Pier 4 (P4) in the Komering Cempaka East Oku water bridge construction project using Ø40cm, Ø45cm and Ø45 cm diameter variations at depths 18,19,20, 19,20,21, and 14,15,16 meters, as well as variations in the square of 40 x 40 cm, 45 x 45 cm and 50 x 50 cm at a depth of 18,19,20, 14,15,16 and 14,15,16 meters. The results of this study the carrying capacity of the existing piles at point P4 is 10333.93 kN, and after varying with different pile sizes using the allpile software, the most efficient variation is Ø40 with a depth of 19 meters, as many as 27 pole spacing between mast 150 cm and volume 64.433 m3 with a difference of 25.64% of the volume of the existing pile, then variation Ø45 with a depth of 18 meters totaling 27 poles spacing between the piles 150 cm and volume 77,256 m3 with a difference of 12.55% from the volume of existing piles.
