STABILISASI LERENG BUATAN DENGAN PENAMBAHAN KAPUR MENGGUNAKAN METODE FINITE ELEMENT (Studi Kasus Kawasan Kantor Pemda Seluma, Talang Saling Kabupaten Seluma)

Seluma regency often occurs landslide disaster and one of them is located in Local Government Authority Seluma area. This study aims to analyze the stability of the slope by finite element method program, so it is known that the safety factor (SF) and the soil type. The study was started by testing physical and mechanical properties of the soil, then slope stability analysis was done by finite element method to find out FK. The result of soil physical properties test shows that the land on the slope of Local Government Authority Seluma area is clay soil. Calculation of slope stability analysis using finite element method by considering the effect of pore water to get the safest result on slope cement stabilization soil 1 Contour A, SF= 1,817 with a slope angle of 34o . The slopes studied in the Local Government Authority in Seluma Regency are all prone to landslides or unsafe because SF is < 1,5. Based on the results of the research from the safest slope, it was concluded that the value of the Safety Factor (SF) of soil stabilization of limestone was 1,817 bigger than the value of the safety Factor (SF) of soil compaction was 1,619 and the value of the safety Factor (SF) of soil compaction was 1,399 bigger than the value of the safety Factor (SF) of the original soil was 1,48
