Abstract :
A bridge is a construction that is used to continue the path through lower obstacles. Fly Over Purwosari is an access to Jalan Slamet Riyadi that connects downtown Surakarta with the surrounding area or access to downtown Surakarta from the direction of Kartosuro (Yogyakarta-Semarang). The purpose of the Purwosari Fly Over construction project is to reduce traffic that occurs at the crossing. In the construction of a construction project, the foundation is the most important thing because it functions to transmit the load of the structure above it to the soil layer below it. The researcher in this case wants to analyze the pile foundation at abutment 1 Fly Over Purwosari which previously used drill pile foundations, so that it can produce an effective foundation selection from the results of the analysis between pile foundations and piles. In Indonesia, the latest bridge loading regulations used are bridge loading SNI 1726: 2016. Calculation of the analysis of the bearing capacity of pile foundations using the Mayerhoff method (1976) with several diameters and pile depths. Calculations based on SPT field data and laboratory data. Calculation of the results of the loading of the bridge (SNI 1725-2016) obtained a maximum axial load P of 2555,799 tons. While the results of the analysis of the carrying capacity of a single pile using the Mayerhoff method (1976) with a diameter of 0.6 m, the results obtained are 280.626 tons, a diameter of 0.8 m is 372.761 tons, and a diameter of 1 m is 425.564 tons. From the results of the calculation of the carrying capacity above, the type of pile foundation with a diameter of 1 m requires less piles than the 1 m diameter borpile pile used in the construction of the Fly Over. The pole requirements of several diameters are, 0.6 diameter needs 28 poles and 30 poles, while the pile only requires 12 poles, 0.8 m diameter needs 10 poles, and 1 m diameter needs 8 poles. From the results of the carrying capacity of the group, it was found that the carrying capacity greater than the axial load to be received in abutment 1 was 2595,052 Tons at 0.6 m diameter, 2695.739 Tons at 0.8 m diameter, and 2652.416 Tons at 0.6 m diameter. 1 meter in diameter, based on the number of poles required in each diameter
