Analisis Penentuan Faktor Keamanan Stabilitas Lereng Menggunakan Metode Fellinius Dan Bishop (Studi Kasus : Jl. Mulyorejo, Kecamatan Ngantang Kabupaten Malang)
Abstract
Kata-kata kunci : stabilitas lereng, nilai faktor keamanan
ABSTRACT
Soil stability on slopes can be disrupted by natural influences, climate and human activities. A landslide occurs because the unbalance of force acting on the slope or the force of the slope area is greater than that of the retaining force on the slope So that required the analyst of stabilias slope to know the Security Factor of the slopes that experienced slippage. From the analysis result using Fellinius and Bishop Method of Security Factor values obtained are: A and B slopes for Fellinius Method: 0.74 and 0.83, while for Slope A and B for Bishop Method: 0.78 and 0.92 which shows that the state of the slope is unstable. Then performed improvements by changing the angle of the slope. The following values are obtained: A and B slopes for Fellinius Methods: 1.62 and 2.66 while A and B slopes for Bishop Methods: 1.94 and 3.25 indicate slopes in a stable state.
