Aplikasi Program Plaxis 2D untuk Menghitung Safety Factor Perkuatan Tebing Sungai Sekanak Sepanjang 240m dengan Menggunakan Sheet Pile

Sheet pile is a part of the construction that serves to hold the soil from collapse. As a result of lateral soil pressure that occurs when there is a change in soil elevation and exceeds the soil shear angle. Slope reinforcement analysis is needed in designing a soil reinforcement. To analyze the strength of the soil, of course, primary data taken in the field is needed, one of which is a soil sample. This research was conducted on the banks of the Sekanak river. Sekanak River passes through several villages including Bukit Lama, Bukit Baru Lorok Pakjo, Talang Semut, and several other villages in the Ilir area. The purpose of this study was to calculate the value of the Safety Factor (SF) from the plan for the construction of sheet piles using sheet pile material. This research uses modeling with Plaxis 2D program. Modeling is carried out to obtain the value of the safety factor on natural slopes. Sheet pile modeling has the greatest safety factor value for each slope of 1.831 for alternatives 1 and 1.934. for alternative 2. The values obtained in alternatives 1 and 2 meet the requirements for cliff reinforcement..
