Abstract :
The foundation planning on the SS BSD Raya Abutment1 (A1) Bridge at the Serpong - Balaraja Toll Road Project Section 1A is the bore pile foundation, the bore pile foundation is used because the results of soil investigation are soft soil which has a high risk of congestion and low bearing capacity.The method used for the analysis of the bearing capacity of the bore pile foundation is the method of analysis with the Reese and O'neill, Meyerhoff, and Kulhawy formulas; finite element method using Allpile software; and (Pile Driving Analyzer) PDA method. In the analysis method, the Kulhawy method was chosen because the value of the lowest bearing capacity was Qu = 876,623 tons and Qizin = 350,649 tons with a decrease in single and group piles of 60,121 mm and 492,466 mm. In calculating the carrying capacity using Allpile, the Qizin results are 671,165 tons and Qu is 1677,912 tons and the PDA method is 1195,5 tons and Qizin is 478,2 tons. The comparison between the analysis method and the PDA method was 26,673%, the computer application analysis method was 56.680%, and the PDA method and the computer application was 39,557%. From the results of the comparison of the three methods, the analysis method (Kulhawy method) was chosen for the bore pile foundation planning.
