Abstract
Jembatan boboh (KLBM 2 STA 18+970-19+336) adalah salah satu bagian dari jalan tol krian-legundi-bunder-manyar yang melintasi jalan raya boboh pada STA 18+970-19+076 dan dibangun secara menerus diatas daerah persawahan dari STA 19+076-19+336. Kondisi eksisting jembatan ini menggunakan sistem struktur gelagar pratekan, memiliki panjang total 366 meter yang dibagi menjadi 8 span dan memiliki 9 pilar struktur beton bertulang yang dicor di tempat. Pada topik Tugas Akhir ini, ruas jalan tol yang dipilih untuk objek alternatif desain struktur adalah pada STA 19+076 – STA 19+283. Penulis melakukan perencanaan alternatif desain menggunakan sistem struktur jembatan slab on pile. Dimana struktur tersebut sangat cocok pada eksisting trase yang melewati daerah persawahan dan pertambakan dengan kondisi tanah yang sangat lunak. Dari segi metode pelaksanaan, struktur slab on pile memiliki kesederhanaan dalam hal pelaksanaan dibandingkan dengan struktur jembatan girder pratekan. Karena struktur tersebut hanya terdiri dari pelat lantai, balok pilehead dan tiang pancang sebagai pengganti peran pilar seperti pada konstruksi jembatan girder pratekan. Sehingga, dalam pekerjaan struktur tersebut tidak memerlukan pekerjaan beton pada struktur bawah dan pekerjaan girder pada struktur atas.
Struktur slab on pile ini menggunakan sistem halfslab precast sebagai bangunan atas, Pilehead dan Tiang pancang sebagai bangunan bawah. Elevasi freestanding tiang pancang bervariasi antara 8 meter sampai dengan 9 meter dengan bentang antar pilehead 6.2 meter dan 6.25 meter. Pada perencanaan ini, analisa struktur menggunakan bantuan software SAP 2000 serta desain menggunakan rumus berdasarkan peraturan SNI 1725:2016 (Pembebanan untuk jembatan), SNI 2833:2016 (Perencanaan Jembatan Terhadap Gempa), SNI 8460:2016 (Perencanaan Geoteknik), dan SNI T-12-2004 (Perencanaan struktur beton untuk jembatan). Sehingga dari hasil perhitungan struktur slab on pile didapatkan jumlah slab precast sebanyak 10 buah dengan lebar 1.25 m dan ketebalan 35 cm setelah komposit, dimensi pile head 0.7 m x 1.4 m, spun pile diameter 60 cm berjumlah 10 buah setiap bentang dengan kedalaman 30 meter. Pada perhitungan pier kolom didapatkan Pier kolom P15 dengan tinggi 10,658 m dan pier kolom P21 dengan tinggi 12,658 m, menggunakan spun pile diameter 60 cm dengan jumlah 60 buah.===============================================================================================
The boboh bridge (KLBM 2 STA 18+970-19+336) is one part of the krian-legundi-bunder-manyar toll road that crosses the boboh highway at STA 18+970-19+076 and is built continuously over the rice fields of STA 19+076-19+336. The existing condition of this bridge uses a prestressed girder structure system, has a total length of 366 meters which is divided into 8 spans and has 9 pillars of reinforced concrete structures that are cast in place. In the topic of this Final Project, the selected toll roads for the alternative object of structural design are STA 19+076 – STA 19+283. The author plans alternative design which is using a slab on pile bridge structure system. Where the structure is very suitable for the existing trace that passes through rice fields and aquaculture areas with very soft soil conditions. In terms of the implementation method, the slab on pile structure has simplicity in terms of implementation compared to the prestressed girder bridge structure. Because the structure only consists of floor slabs, pilehead beams and piles as a substitute for the role of pillars as in the construction of prestressed girder bridges. Thus, the structural work does not require concrete work on the lower structure and girder work on the upper structure.
The slab on pile structure design uses a precast halfslab system as the superstructure, Pilehead and piles as the substructure. The freestanding pile elevation varies between 8 meters to 9 meters with a span between pileheads of 6.2 meters and 6.25 meters. The structural modeling is designed according to the initial calculation of the structural components and the elevation in the modeling is taken from the highest elevation in the structure to find out how the behavior of structures that have high freestanding. In this planning, structural analysis using SAP 2000 software and design using formulas based on SNI 1725:2016 (Loading for bridges), SNI 2833:2016 (Bridge Planning Against Earthquake), SNI 8460:2016 (Geotechnical Planning), and SNI T -12-2004 (Planning of concrete structures for bridges). From the calculation of the slab on pile structure, it is found that the number of precast slabs is 10 pieces with a width of 1.25 m and a thickness of 35 cm after the composite, the dimensions of the pile head are 0.7 m x 1.4 m, the spun pile diameter of 60 cm is 10 pieces per span with a depth of 30 meters. In the calculation of the column piers, the column pier P15 with a height of 10,658 m and the column pier P21 with a height of 12,658 m, using a spun pile diameter of 60 cm with a total of 60 pieces.
