Abstract

Jembatan Tumbang Samba berlokasi di Kalimantan Tengah yang menghubungkan Desa Telok dan Desa Samba Danum, dengan total panjang 568 m yang terdiri atas struktur Modified Network Tied Arch Bridge (128 m) serta struktur komposit (220+220)m. Banyaknya pilar pada jembatan tersebut menjadikannya kurang efisien karena dapat mengurangi effective linear waterway pada sungai. Oleh karena itu, ditawarkan sebuah ide Modifikasi Desain Jembatan Tumbang Samba Menggunakan Double Planes System Cable Stayed. Jembatan cable stayed adalah jembatan yang menggunakan kabel untuk menopang beban lantai dek jembatan. Modifikasi ini direncanakan menggunakan 2 buah pylon sehingga penggunaan pilar pada jembatan tersebut lebih sedikit dibandingkan dengan struktur jembatan eksisting. Gelagar jembatan direncanakan menggunakan Steel Orthotropic Trapezoidal Box Girder yang mana dapat meningkatkan kekakuan jembatan. Metode pelaksanaan konstruksi jembatan direncanakan menggunakan metode balanced cantilever dengan backward construction stage analysis. Perencanaan modifikasi dimulai dari studi literatur dan pengumpulan data, preliminary design, perhitungan pembebanan, pemodelan dan analisis struktur sekunder dan primer, kontrol statis dan dinamis, analisis staging, perencanaan angkur dan sambungan, analisis satu kabel putus, perencanaan perletakan, hingga analisis staging. Dasar perencanaan jembatan mengacu pada peraturan SNI 1725:2016, SNI 2833:2016, dan SNI 1729:2020.

The Tumbang Samba Bridge is located in Central Kalimantan and connects the villages of Telok and Samba Danum, with a total length of 568 meters. This bridge consists of a Modified Network Tied Arch Bridge structure (128 meters) and a composite structure (220+220 meters). The numerous pillars of the bridge make it inefficient as they reduce the effective linear waterway of the river. Therefore, an idea is proposed to modify the design of the Tumbang Samba Bridge using a Double Planes System Cable Stayed. A cable-stayed bridge is a bridge that uses cables to support the load of the bridge deck. This modification is planned to use two pylons, thereby reducing the number of pillars on the bridge compared to the existing bridge structure. The bridge girder is planned to use a Steel Orthotropic Trapezoidal Box Girder which can increase the stiffness of the bridge. The bridge construction method is planned to use the balanced cantilever method with backward construction stage analysis. The modification planning starts from literature study and data collection, preliminary design, load calculation, modeling and analysis of secondary and primary structures, static and dynamic control, anchor and joint planning, single cable break analysis, bearing planning, and finally staging analysis. The bridge planning is based on SNI 1725:2016, SNI 2833:2016, and SNI 1729:2020 regulations.
