Abstract

Dermaga PSF merupakan fasilitas krusial yang dibutuhkan untuk distribusi peralatan berat. Lokasinya berada di tepi Sungai Wain dengan jenis tanah ekspansif. Berdasarkan hal tersebut, maka diperlukan review desain struktur terhadap bahaya kelongsoran dan penentuan alternatif perubahannya. Dalam melakukan analisis digunakan program bantu Plaxis dan SAP2000. Program Plaxis digunakan untuk meninjau permasalahan tanah dan stabilitas struktur, adapun SAP2000 digunakan sebagai kontrol kekuatan struktur terhadap kapasitas yang dimiliki. Berdasarkan hasil yang didapatkan, struktur dermaga sudah aman dari bahaya longsor dan memenuhi kriteria persyaratan terhadap kontrol struktur yang dilakukan. Sesuai dengan output Plaxis, deformasi tanah yang terjadi pada rencana desain dermaga adalah sebesar 52,83 mm di mana melebihi batas ijinnya yaitu 25,4 mm. Modifikasi struktur pada bagian plat lantai dilakukan dengan maksud agar plat lantai dapat mendukung tie-rod dalam menahan gaya tarik yang terjadi pada struktur. Dari hasil pemodelan modifikasi tersebut didapatkan perubahan nilai deformasi tanah menjadi 22,92 mm adapun gaya aksial yang bekerja pada tie-rod berubah dari 294,084 kN menjadi 204,451 kN. ================================================================================================== PSF wharf is a crucial facility needed for heavy equipment distribution. The location is on the riverside of the Wain River which has expansive soil types. Based on those, it is necessary to review the structural design in case against sliding hazard and to determine the alternative changes. During the analysis, Plaxis and SAP2000 as auxiliary programs are used. The Plaxis program is used to review the soil problems and structural stability, while SAP2000 is used to control the strength of the structure on its capacity. Based on the results, the wharf structure was safe from landslide hazards and conforms the requirements for structural control. In accordance with the Plaxis output, the soil deformation that occurs in the design of the wharf is 52,8 mm, which exceeds the permit limit of 25,4 mm. The modification of the structure of the plate section is carried out with the intention that the plate would support the tie-rod in resisting the tensile forces that occur in the structure. From the results of the modification modeling, the value of soil deformation was change into 22,92 mm, while the axial force acting on the tie-rod changed from 294,084 kN to 204,451 kN.
