The foundation is a construction that continues the burden of the upper structure and passes it on to the soil below it. A bored pile foundation is now an option in working on structures in densely populated areas and tall buildings. The purpose of this study is to calculate and compare the carrying capacity of the bored pile foundation based on N-SPT data with the O 'Neil & Reese, and Reese & Wright methods, while the Loading test data with the interpretation of the Davisson method and the Mazurkiewicz method. The results of calculations based on N-SPT data, the average ultimate carrying capacity of the foundation with the O’neil & Reese method of 1211.61 tons, Reese & Wright of 1235.02 tons. While the Interpretation of Loading test method for Marzukiewicz is 1267.00 tons, Davisson is 850.40 tons, and the carrying capacity of PDA test results is 121.72 tons. From the calculation of the bearing capacity of the consecutive foundation of the smallest is the Davisson method, the O'neil & Reese method, the PDA test method, the Reese & Wright method, and finally the Mazurkiewicz method.

The pile foundation is one of the deep foundation types commonly used to support building loads when hard soil layers are deeply located. To determine the ultimate bearing capacity of a pile foundation of the load test results, there are several methods commonly used to interpretation test results such as Davisson method, Mazurkiewich method, Chin method, Buttler Hoy method and De Beer method. The aim of this study was to determine the characteristics of soft soil and bakau piles used in the study and to analyze the size of the bearing capacity ultimate of pile foundation that is modeled on a small scale in the laboratory. From the test results of material characteristics of the soil used is organic clay type with medium plasticity with specific gravity 2.75, liquid limit, LL = 50.36% and plasticity index, PI = 13.2%. While the results of testing the characteristics of bakau piles obtained average water content of 21.58%, tensile strength of 18.51 MPa, compressive strength of parallel fiber 23.75 MPa and perpendicular fiber 14.10 MPa, bending strength 106, 22 MPa, and strong split 29.91 MPa. From the result of loading test of the foundation model in the laboratory, it is found that the ultimate bearing capacity of the model without foundation is 41.00 kN with the ultimate settlement of 14.00 mm, the model of the 20 cm long bakau piles foundation is 52.00 kN with the ultimate settlement of 13.00 mm, the foundation model a 30 cm long bakau piles foundation of 54.00 kN with a 10.00 mm ultimate settlement, a 40 cm long bakau piles foundation model of 56.00 kN with an ultimate settlement of 8.50 mm.

End Bearing Pile

Raft pile is an option for high rise building that has more than 30 stories on soft to moderate soil conditions. Either spun pile or bored pile can be used as the pile foundation. This study focuses on 34-story building that is constructed near electric rail train station, where the soil type is dominantly clay with average N-SPT 20 – 30, there is also thin layer of soil with N-SPT 60. The study compares two types of piles, 30 m depth floating pile and 32 m depth end bearing pile, where the raft thickness is 2 m. The study was conducted by calculating the bearing capacity and settlement with formulas based from correlations of N-SPT and the N-SPT data. Midas 3D also used to simulate the settlement of the building and settlement around the building. The results show that for bored pile with depth of 30 and 32 m respectively has settlement of 20,757 cm and 3,0475 cm while the settlement around the building consecutively is around 10 – 11 cm and 1,5 – 2 cm. Bearing capacity of bored pile with 30 m depth is around 1593,6779 – 5382,5954 kN while bored pile with 32 m depth  is around 1978,9153 – 6021,3859 kN.Fondasi rakit merupakan salah satu pilihan yang dapat digunakan untuk bangunan tinggi lebih dari 30 lantai pada tanah kondisi lunak sampai sedang. Untuk jenis fondasi tiang dapat digunakan tiang bor atau tiang pancang. Dalam penelitian ini dilakukan studi fondasi bangunan 34 lantai yang didirikan dekat dengan stasiun kereta rel listrik di mana lapisan tanah dominan lempung dengan N-SPT rata-rata 20 – 30 dan juga ada nilai N-SPT 60 namun berupa lapisan tipis. Studi dilakukan dengan membandingkan dua jenis tiang yaitu tiang dengan daya dukung friksi kedalaman 30 m dan tiang dengan daya dukung ujung kedalaman 32 m dengan ketebalan fondasi rakit 2 m. Studi dilakukan dengan menghitung daya dukung serta penurunan menggunakan pendekatan rumus-rumus berdasarkan data N-SPT dan korelasi dari data N-SPT, juga dilakukan simulasi Midas 3D untuk mengetahui besar penurunan yang terjadi di sekitar bangunan. Dari hasil studi banding diperoleh penurunan fondasi tiang 30 m dan tiang 32 m berturut-turut sebesar 20,757 cm dan 3,0475 cm sedangkan penurunan sekitarnya diperoleh berturut-turut 10 – 11 cm dan 1,5 – 2 cm. Daya dukung yang diperoleh tiang 30 m berkisar 1593,6779 – 5382,5954 kN dan tiang 32 m berkisar 1978,9153 – 6021,3859 kN.

Abstract. In the presented paper, reverse push-out test method was put forward and applied in the ultimate bearing capacity experiments of studs with concrete slab in tension. Ultimate bearing capacity experiments were carried out on 22 reverse push-out specimens composed of C50 or C40 concrete, 14MnNbq steel girder and Φ22studs. Results showed that ultimate bearing capacity of studs, pu, in tensile concrete slab is controlled by concrete failur, concrete strength, studs arragement and reinforcement ratio are the main influence factors of pu. Compared with that in compressive concrete, pu of Φ22 studs in tensile concrete is reduced about 30% averagely. According to the test results, a fitted load-slip relationship curve and a regression formula of pu for studs in tensile concrete were put forward, calculated results were in good agreement with the test results.

The Cibitung - Cilincing toll road is faced with problems across many rivers and marshlands where the swampland is identified as clay. In building construction, the foundation is very important in bearing the burden of working on the upper construction. This Final Project contains the calculation of the carrying skin capacity and the end resistance of the pile using the Suyono method. S and Nakazawa (1990) based on N-SPT data and dynamic methods using the formula of Hiley (1930) based on the pile driving record data, then proceed to the calculation of the carrying capacity of the pile group, after that calculating the decrease of the pile using the Vesic method (1977). From the results of the analysis conducted by the author in calculating the bearing capacity to using N-SPT data and pile driving record data, the author gets that from the pile diameter of 50 cm, the carrying capacity of a single-pole is 66-ton, obtained using the method of Suyono S and Nakazawa, based on the formula of Hiley, it is obtained 139.34 tons, and settlement that occurred in the pile group foundation was an immediate settlement is 11.2 cm and a consolidation settlement is 6.2 cm.
