Dalam perencanaan ini, dimensi dinding penahan tanah tipe gravitasi yang ada di lapangan akan didesain ulang menjadi tipe kantilever dengan dimensi yang lebih ramping. Perencanaan dinding penahan tipe kantilever menggunakan metode Rankine dan program Geo5 dengan 4 macam kondisi dinding penahan dan akan ditinjau stabilitas guling, geser dan kapasitas daya dukung tanah dinding penahan. Dari hasil penelitian dimensi dinding penahan tanah yang direncanakan adalah tipe kantilever dengan lebar (B) 7,55 m; tinggi (H) 5,1 m; B1 = 6,53 m; B2 = 0,3 m; B3 = 0,51 m; H1 = 4,59 m; H2 = 0,51m. Nilai faktor aman dinding penahan tanah menggunakan metode Rankine dan program Geo5 terhadap guling pada kondisi 1 17,683 dan 11,03; kondisi 2 21,3652 dan 13,91; kondisi 3 19,9739 dan 12,11; kondisi 4 9,4524 dan 15,51. Nilai faktor aman dinding penahan tanah menggunakan metode Rankine dan program Geo5 terhadap geser pada kondisi 1 5,0168 dan 3,17; kondisi 2 25,6034 dan 4,29; kondisi 3 5,4780 dan 3,31; kondisi 4 13,2537 dan 4,57. Nilai faktor aman dinding penahan tanah menggunakan metode Rankine dan program Geo5 terhadap kapasitas daya dukung tanah pada kondisi 1 12,0879 dan 15,89; kondisi 2 22,4037 dan 29,33; kondisi 3 113,3604 dan 7,08; kondisi 4 18,4200 dan 26,94. Nilai tertinggi stabilitas dinding penahan tanah kantilever terhadap geser adalah pada kondisi 2 yaitu 25,603, sedangkan untuk tipe gravitasi pada kondisi 2 dengan nilai 10,240.

In this design, the dimensions of the existing gravity-type retaining wall in the field will be redesigned to a cantilever type with a slimmer dimension. Cantilever retaining wall plan using Rankine method and Geo5 program with 4 kinds of retaining wall conditions and will be reviewed the stability of overturning, slip and bearing capacity failure of retaining walls. From cantilever type retaining wall design planned with width (B) 7.55 m; high (H) 5.1 m; B1 = 6.53 m; B2 = 0.3 m; B3 = 0.51 m; H1 = 4.59 m; H2 = 0.51m. Safety factor against overturning in Rankine method and Geo5 program in first condition are 17.683 and 11.03; second condition are 21.3652 and 13.91; third condition are 19.9739 and 12.11; fourth condition are 9.4524 and 15.51. Safety factor against slip in Rankine method and Geo5 program in first condition 5.0168 and 3.17; second condition are 25.6034 and 4.29; third condition are 5.4780 and 3.31; fourth condition are 13.2537 and 4.57. Safety factor against bearing capacity failure in Rankine method and Geo5 program in first condition are 12.0879 and 15.89; second condition are 22.4037 and 29.33; third condition are 13.3604 and 17.08; fourth condition are 18.42 and 26.94. The highest safety factor cantilever type retaining wall against slip in second condition is 25.603, while in gravity type in second condition is 10.240.
