Abstract

Submerged Floating Tunnel (SFT) atau Jembatan Archimedes adalah suatu teknologi inovatif infrastruktur di bidang transportasi yang digunakan untuk menghubungkan antara pulau satu dengan pulau lainnya. Faktor ekonomis adalah alasan utama SFT, karena tidak memerlukan pilar. Secara prinsip SFT memanfaatkan gaya buoyancy yang terjadi di air. Rasio perbandingan antara gaya buoyancy dengan beban-beban vertikal pada SFT disebut buoyancy weight ratio (BWR). BWR merupakan parameter utama dalam stabilitas struktur SFT, maka dilakukan studi dalam menentukan nilai BWR. Hal ini karena setiap wilayah perairan mempunyai gaya buoyancy yang berbeda-beda. Studi tentang BWR dilakukan dalam analisa menggunakan software Finite Element Methode (FEM) SAP2000 v.14.2.2. Dari analisa diperoleh hasil efektif nilai BWR 1,3. Hasil efektif tersebut digabungkan dengan hasil efektif parameter lainnya, selanjutnya dibuat pemodelan efektif dan dilakukan analisa. Hasil pemodelan efektif struktur prototype SFT adalah BWR 1,3; perletakan ujung tunnel sendi-sendi; dan konfigurasi kabel sudut 54o. Menggunakan define propertiesiv “cable”, dan pemberian initial tension sebesar 26,1 kN (spesifikasi material kabel) dengan tipe analisa gelombang non linier

Submerged Floating Tunnel (SFT) or Archimedes Bridge is an innovative technology in the field of transport infrastructure that is used to connect between the islands with other islands. Economic factors are the main reason SFT, because it does not require a pillar. In principle, the SFT utilizes buoyancy force that occurs in water. The ratio of the buoyancy force with the vertical loads on the SFT is called buoyancy weight ratio (BWR). BWR is a major parameter in the stability of the structure of SFT, then conducted a study to determine the value of BWR. This is because each region has waters buoyancy force different. The study of BWR done in software analysis using Finite Element Method (FEM) SAP2000 v.14.2.2. From the analysis of the results obtained by the effective value of BWR 1,3. The effective yield effective results coupled with other parameters, hereafter made effective modeling and analysis. Effective modeling results SFT prototype structure is BWR 1,3; placement end of the tunnel joints; 54o angle and cable configurations. Using properties define "cable", and the provision of initial tension of 26.1 kN (cable material specification) with the type of non-linear wave analysis
