Abstract
Bored pile foundation is a pile foundation whose installation is done by drilling the ground first. Carrying capacity analysis studies the ability of the soil to support the load on the foundation structure located on it. Bearing capacity represents the shear resistance of the soil to resist settlement due to loading, that the shear resistance that the soil can exert along its shear planes. The end bearing capacity of the bored pile foundation in the Student Center Untirta Sindangsari building project was calculated based on N–SPT data using the Reese & Wright method and Meyerhof method. This study aims to determine the carrying capacity of the bored pile foundation and settlement based on N–SPT data using the Reese & Wright, Meyerhof method and Plaxis 2D methods on the Untirta Sindangsari Student Center building project. Calculation of the ultimate bearing capacity of bored pile foundation with a diameter of 0.6 m and a length of 12 m on Bore Hole 01 (BH–11.1) P1' based on N–SPT data using the Meyerhof method which is obtained at Qu = 1197,066 KN/m2 and Reese & Wright method, which is obtained at Qu = 688,893 kN/m2 not much different from The results of calculations using Plaxis software are Qu = 653.758 kN/m2 (before consolidation) and 693.025 kN/m2 (after consolidation). The decrease in bored pile analytically is 0.0062 m, and with the Plaxis program it is found that the decrease before consolidation is 0.01355 m and after consolidation is 0.01469 m.

| Additional Information: | Pondasi bored pile adalah pondasi tiang yang pemasangannya dilakukan dengan mengebor tanah lebih dahulu. Analisis daya dukung mempelajari kemampuan tanah dalam mendukung beban pondasi struktur yang terletak di atasnya. Daya dukung menyatakan tahanan geser tanah untuk melawan penurunan akibat pembebanan, yaitu tahanan geser yang dapat dikerahkan oleh tanah di sepanjang bidang-bidang gesernya. Daya dukung ujung pondasi bored pile pada proyek Gedung Student Center Untirta Sindangsari dihitung berdasarkan data N–SPT menggunakan metode Reese & Wright dan metode Meyerhof. Penelitian ini bertujuan untuk mengetahui nilai daya dukung pondasi bored pile dan penurunan berdasarkan data N–SPT menggunakan metode Reese & Wright, Metode Meyerhof dan Plaxis 2D pada proyek pembangunan Gedung Student Center Untirta Sindangsari. Perhitungan daya dukung ultimit pondasi bored pile dengan diameter 0,6 m panjang 12 m pada Bore Hole 01 (BH–11.1) P1’berdasarkan data N–SPT menggunakan metode Meyerhof didapat sebesar Qu = 1197,066 KN/m2, dan berdasarkan metode Reese & Wright yaitu didapat sebesar Qu = 688,893 kN/m2 tidak jauh berbeda dengan hasil perhitungan dengan software plaxis yaitu didapat sebesar Qu = 653,758 kN/m2 (sebelum konsolidasi) dan 693,025 kN/m2 (sesudah konsolidasi). Penurunan bored pile secara analitis sebesar 0,0062 m, dan dengan program plaxis didapat penurunan sebelum konsolidasi sebesar 0,01355 m dan setelah konsolidasi sebesar 0,01469 m. | |||||||||
