Abstract
Fondasi bore pile merupakan konstruksi bangunan yang berfungsi untuk menopang beban bangunan di atasnya. Hal yang perlu diperhatikan dalam perencanaan fondasi bore pile ialah dengan memperhitungkan nilai daya dukung dan penurunannya. Tujuan penelitian ini adalah untuk menghitung dan membandingkan nilai daya dukung dan penurunan fondasi diameter 40 cm, 50 cm dan 60 cm dengan metode Reese and Wright dan Reese and O’neil pada proyek transmisi GISTET 500 kV Muara Karang Baru. Hasil penelitian menunjukkan bahwa nilai daya dukung tiang kelompok tipe P7A yang dihitung berdasarkan data SPT pada titik BH-4 diameter 40 cm, 50 cm dan 60 cm dengan metode Reese and Wright berturut – turut sebesar 2636,9357 kN, 2652,4911 kN, 2667,7913 kN dan metode Reese and O’neil berturut – turut sebesar 2591,7643 kN, 2623,0389 kN dan 2554,2373 kN. Dimana kedua metode tersebut memenuhi beban aksial total (Pu) sebesar 2483,13 kN. Rancangan tiang yang diambil yaitu pada metode Reese and O’neil diameter 40 cm dan jumlah tiang 15, yang memiliki nilai daya dukung kritis atau mendekati beban kerja maksimal. Hasil penurunan pada metode Reese and O’neil diameter 40 cm tersebut juga aman dan memiliki nilai penurunan yang rendah, yaitu sebesar 7,5923 cm dengan penurunan izin sebesar 15,8667 cm.
Foundation Bore pile is a building construction that functions to support the load of the building above it. The thing that needs to be considered in planning the bore pile is to consider the value of the bearing capacity and its settlement. The purpose of this study was to calculate and compare the value of bearing capacity and foundation settlement with diameters of 40 cm, 50 cm and 60 cm using the Reese and Wright and Reese and O'neil methods on the 500 kV Muara Karang Baru GISTET transmission project. The results showed that the value of the pile bearing capacity of the P7A type group which was calculated based on SPT data at point BH-4 with a diameter of 40 cm, 50 cm and 60 cm using the Reese and Wright, respectively, was 2636.9357 kN, 2652.4911 kN, 2667. ,7913 kN and Reese and O'Neil method 2591.7643 kN, 2623.0389 kN and 2554.2373 kN, respectively. Where both methods meet the total axial load (Pu) of 2483.13 kN. The pile design taken is the Reese and One'il diameter of 40 cm and the number of piles 15, which has a critical bearing capacity value or is close to the maximum working load. The result of the reduction in the Reese and O'Neil diameter of 40 cm is also safe and has a low reduction value, which is 7.5923 cm with a decrease in clearance of 15.8667 cm.
