Analisis Stabilitas Lereng dengan Alternatif Perkuatan Menggunakan Software Plaxis 2D dan Slope/w (Studi Kasus : Proyek Pembangunan Kampus Baru UNTIRTA Sindangsari)

A slo . pe is a field th . at has a certain slo . pe and has the pote . ntial for land . slides to occur i . f it is in an unstabl . e condition. This . condition mu . st be consid . ered becaus . e it can cause . losses such . as dam . age to infras . tructure. F . or this reason . , the stabi . lity of a sl . ope needs . to be analyz . ed so that t . he shear st . rength of th . e slope and . its saf . ety factor are . known. Based . on what has bee . n stated p . reviously, t . he resea . rcher . s condu . cted an anal . ysis of the . stabilit . y of the ped . estrian sl . opes in the . New Campu . s Construct . ion Project of the Sultan Ageng Tirtayasa University located in Sindangsari Village, Serang Regency, Ba . nten. The . purpose of this s . tudy was to det . ermine the value . of the safe . ty factor f . or the origi . nal slope and . the slop . e with alter . native reinfo . rcement. In this s . tudy, analysi . s will be carried . out using the Bisho . p method and soft . ware Plaxis 2D and Slo . pe/w. The re . sults of the analysis ca . lculation on the orig . inal slope con . ditions using Slo . pe/w obta . ined SF = 1,117, using Plaxis 2D short term obtained SF = 1,111 while the long term obtained SF = ,101 and using manual calculations the Bishop method obtained SF = 1,107. The results of the analysis on the slope conditions of bored pile using Plaxis 2D with short term obtained SF = 1,310 while long term obtained SF = 1,319, and using manual calculations the Bishop method obtained SF = 1,317. Then the results of the analysis on the slope conditions of sheet pile using Plaxis 2D with short term obtained SF = 1,392 while long term obtained SF = 1,404 and using m . anual calc . ulations the Bishop method obtained SF = 1,406.
