“…Sehingga desain struktur sebuah bangunan akan semakin berkembang dari waktu ke waktu dan muncul berbagai alternatif desain yang dapat digunakan. Fondasi berfungsi sebagai penerima beban di atasnya untuk selanjutnya disalurkan ke tanah harus dirancang hingga memenuhi persyaratan agar dapat menahan beban sehingga tidak menyebabkan kegagalan pada struktur fondasi juga bangunan di atasnya [1] [4] [5] [7] [8] [12]. Berdasarkan SNI 8460:2017 mengenai Persyaratan Perancangan Geoteknik, rancangan fondasi harus memenuhi persyaratan kekuatan (strength requirement) dan memenuhi persyaratan penurunan (serviceability requirement).…”

ABSTRAKPada artikel ini akan dibahas analisis kapasitas fondasi rakit dengan tambahan fondasi tiang (piled raft) pada Pegadaian Tower, Jakarta Pusat. Analisis dilakukan berdasarkan SNI 8460:2017 yaitu fondasi harus memenuhi persyaratan kekuatan terhadap gaya vertikal maupun horizontal dengan faktor keamanan yang mencukupi. Berdasarkan hasil penyelidikan tanah, Pegadaian Tower berada di atas lapisan tanah lunak hingga kedalaman 20 meter, terdapat lapisan lensa tanah, dan tidak ditemukan lapisan tanah keras dengan N > 60 hingga kedalaman 80 meter, sehingga dipilih jenis fondasi piled raft. Metodologi analisis dimulai dengan menentukan pembebanan berdasarkan standar yang berlaku, melakukan analisis kapasitas fondasi raft dan bored pile. Berdasarkan hasil perancangan, didapat diameter bored pile dengan diameter 1,2-meter pada kedalaman 35-meter dan daya dukung aksial sebesar 3928,87, dibutuhkan sebanyak 220 tiang, sehingga menghasilkan daya dukung 468.628,28 kN (81,848%). Daya dukung fondasi raft sebesar 54,25 kN/m2 (18,15%) dengan ketebalan 1,6 meter.Kata kunci: piled raft, bored pile, daya dukung fondasi, penurunan fondasiABSTRACTIn this article, we will discuss the analysis of the capacity of the piled-raft foundation at Pegadaian Tower, Central Jakarta. The analysis was carried out based on SNI 8460: 2017, namely the foundation must meet the strength requirements for vertical and horizontal forces with an adequate safety factor. Based on soil investigation, Pegadaian Tower stood on top of a soft soil layer up to a depth of 20 meters, there is a layer of soil lenses, and no hard soil layer with N > 60 is found up to a depth of 80 meters, so the piled raft foundation type was chosen. Methodological analysis begins with determining the loading based on applicable standards, analyzing the capacity of raft foundations and bored piles. Based on the results, bored pile diameter with a diameter of 1.2-meters at a depth of 35-meters and an axial carrying capacity of 3928,87 kN, 220 piles are needed, resulting in a carrying capacity of 468.628,28 kN (81,848%). The bearing capacity of the raft foundation is 54,25 kN/m2 (18,15%) with a thickness of 1,6 meters.Keywords: piled raft, bored pile, foundation bearing capacity, foundation settlement

“…[4], [5], [6], [7]. However, with the development of various methods of analyzing the bearing capacity of deep foundations, it is necessary to determine which method estimates the closest value of the bearing capacity prediction data compared to the bearing capacity of the test results in the construction stage.…”

Prediction of the bearing capacity of deep foundations using analytical methods from the results of the standard Penetration Test has been carried out until now due to practical consideration. However, with the many types of empirical formulas proposed by various researchers, it is necessary to test the validity of the values predicted by the empirical formulas. During the construction stage, the bearing capacity of deep foundations can be checked using the Pile Driving Analysis (PDA) Test. This study aimed to compare the foundation bearing capacity prediction results using analytical methods of Luciano Decourt (1982), Reese and O'Neil (1999), and Building Standard Law of Japan with the results from PDA test. The comparison indicate that the analytical method of Luciano Decourt (1982) predict bearing capacity with the smallest error rate, which is 1.97% to 38.99% with safaty factor (SF) 2 to 3 on a relatively homogeneous and heterogeneous soil conditions. Prediction of bearing capacity of bored pile foundations using analytical methods O'Neil & Reese (1999) and Building Standard Law of Japan provide better performance for soil types which is dominated by cohesive soils with safety factor (SF) 2.
