In order to study the theory and application of the pile foundation underpinning technology, 3 local node models of underpinning structures with a similarity ratio of 1/1 were made and the progressive repeated static loading tests were conducted. The shear and antislip properties of the joint are studied, and the improved formula for calculating the shear capacity is proposed. The results show that a planting bar plays a major role in shear resistance, and the hoop rate can improve the shear capacity of the interface. The new formula for calculating the shear-bearing capacity is proposed, and the calculation results of the formula of shear-bearing capacity are in good agreement with the experiment results. It is completely feasible to use this formula to calculate the shear-bearing capacity of the pile foundation underpinning structure. During the test, the bearing capacity of the model is good, which proves the reliability of the underpinning technology is good, and it can provide experimental and theoretical basis for the underpinning of similar projects.

ABSTRACTThe Government of Indonesia is accelerating the development of railway infrastructures. MRT is a milestone in the development of railway infrastructures in Indonesia since 2013. The elevated construction uses a single pier structure with a main reinforcement bar diameter of 40 mm. However, the conventional overlapping connection is unsuitable; hence it used a mechanical coupler connection. This research focused on the quality and cost comparison of using a mechanical coupler as a reinforcing connection in the MRT CP 103 Project's pier construction. The variables which would be studied were conventional connection and mechanical coupler connection. There were two stages in this research: quality testing in an independent laboratory and a cost comparison analysis. The data used were primary data from quality testing results, and secondary data were the project volume and unit price. The project sample in this research was MRT CP 103 Project with Pier AP 29 as the case study. The analytical approach used was descriptive analysis by making a comparison of the two variables. According to the quality test results, the tensile strength of the reinforcement was 665.56 N/mm2 and the mechanical coupler tensile strength was 626.33 N/mm2 . According to the calculation results of the case study on Pier AP29, it was found that the price difference was IDR2,246,622 or 6.17% cheaper than conventional connection. Further analysis showed that the mechanical coupler connection with 40 mm diameter was very effective because it was cheap. This research can be used as a reference in the alternative selection of reinforcement connection.Keywords : Quality, Cost, Mechanical Coupler; Pier; MRT CP 103 ProjectABSTRAKPembangunan infrastruktur kereta api sedang dipercepat oleh Pemerintah Indonesia.

General Method

The foundation is a part of the structure that functions as a support for the building and distributes the burden on it (upper fabric) or the soil layer with a stable enough carrying capacity. In planning the foundation for a structure can use several types. The selection of the foundation to be used based on the weight of the building. The construction of the C story building seven-story University requires a strong foundation. The pile foundation was chosen because it was relatively fast, easy, and yielded hard soil at 5.6 m. In this calculation, three methods as a Trofimankove method and the Meyerhoff method and the General Method Method. Pile foundation planning has a planned load of Qu 231 Ton. The calculation of the three ways obtained more efficient results, namely the count with a Meyerhoff method equal to 82.21. The number of single piles that are close to one pile cap is four poles, so the calculation formula of the Pall piles group is 232.82 tons. Thus it can be concluded that Pmax <Pall 231 Ton <232.82 Ton, which means that it meets the requirements.Pondasi adalah bagian struktur yang berfungsi sebagai penopang bangunan dan menyalurkan beban diatasnya (upper structure) atau lapisan tanah yang memiliki daya dukung yang cukup kuat . Dalam merencanakan pondasi untuk suatu struktur dapat menggunakan beberapa macam tipe pondasi. Pemilihan pondasi berdasarkan fungsi bangunan atas yang akan dipikul oleh pondasi tersebut, berdasarkan beban dan beratnya bangunan atas kedalaman tanah dimana bangunan tersebut didirikan. Pembangunan gedung C berlantai 7 Universitas Kadiri memerlukan pondasi yang kuat. Pondasi tiang pancang dipilih karena pekerjaan relatif cepat, mudah dan hasil sondir tanah keras pada 5,6 m. Pada perhitungan ini digunakan tiga metode yaitu metode Trofimankove dan metode mayerhoff serta Metode cara Umum. Perencanaan pondasi tiang pancang memiliki beban rencana sebesar Qu 231 Ton. Dari perhitungan ketiga metode didapat hasil yang lebih efisien yaitu pada perhitungan dengaan metode mayerhoff yaitu sebesar 82,21. Jumlah tiang tunggal yang mendekati pada satu pile cap adalah 4 tiang, sehingga diperoleh dari rumus perhitungan Pall tiang kelompok 232,82 Ton. Dengan demikian dapat disimpulkan Pmaks < Pall 231 Ton < 232,82 Ton, yang artinya memenuhi syarat.
