Analisis Stabilitas Lereng Menggunakan Software Plaxis 8.6 Dengan Dinding Penahan Tanah (Retaining Wall) (Studi Kasus Ruas Jalan Nasional Banda Aceh-Medan Sta 83+135 Gunung Seulawah)

Abstract

Road infrastructure is very important and is a key enabler for the economy. If the road infrastructure was damaged or had various problems such as sliding, the movement of goods and passengers will be hampered and delayed to the acceleration of development in the local area. The landslide and movement of groundwater is a problem that often occurs repeatedly on some streets. Therefore, it is necessary to study the strengthening of the slopes at the bottom of the road construction with retaining wall. This study aims to analyze slope stability by getting numbers Safety Factor (FK). The analysis is used to analyze the stability of slopesusing the finite element method with the help of software Plaids, The scope of this review includes the calculation of slope stability at the national road from Banda Aceh - Medan Sta. 83 + 185 Mount Selawah. The results of slope stability analysis on the existing condition by using Plaxis software at the point of a review is not safe (FK 1.25). Thus, it is done handling the retaining wall, installation of anchors. Based on the analysis of slope stability after being given the strengthening of the slopes with a retaining wall and the installation of anchors using Plaxis software under the influence of traffic load in an unsafe condition (FK 1.25). Then additional handling is done by changing the angle of the slope so that the value of the safety factor (FK) 1.25.

The Analysis of Slope Stability using The Simplified Bishop Method and Geometry of Retaining Walls in Palaran District, Samarinda City, East Kalimantan Province

“…Adapun tujuan penelitian ini dilakukan agar dapat mengetahui nilai Faktor keamanan lereng pada daerah longsoran penelitian tepatnya di Kecamatan Palaran, mengetahui bagaimana geometri dinding dan stabilitas dinding penahan tanah yang tepat di lokasi penelitian. Namun demikian, batasan masalah dalam penelitian ini, diantaranya adalah analisa kestabilan lereng dengan perhitungan faktor keamanan hanya menggunakan Software Rockscience Slide v.6.0 dengan metode Bishop Simplified sebagaimana dimaksud oleh (Pragustus, Mandagi, & A. E., 2019).…”

Analisis Penurunan Badan Jalan Km 605+400 Ruas Jalan Subulussalam–lipat Kajang Diperkuat Pondasi Cakar Ayam Modifikasi

“…Parameter tanah ini merupakan data yang digunakan untuk memperoleh hasil perhitungan analisis konsolidasi pada badan jalan. Data yang digunakan untuk analisis konsolidasi pada badan jalan dengan menggunakan program Plaxis 2D (Wirhadi et al, 2018); (Bowles, 1993) adalah berat volume tanah (γ), kohesi (c), dan sudut geser () yang diperoleh dari hasil pengujian sampel tanah pada Ruas Jalan Subulussalam-Lipat Kajang Km 605+400. Sedangkan untuk Poisson ratio (υ), modulus Young (E ref ) dan koefisien permeabilitas tanah (k) diperoleh dari hasil interpretasi sesuai jenis tanah yang didiskripsikan setelah pengujian.…”
