Abstract :
Geographically Sukabumi has diversed soil surface elevation due to geological process till directly form a slope which vulnerable to landslides. Rumah Perlindungan Sosial Tresna Werda (RPSTW) Bogor project is one of common problem example in the construction field and the demand of information about structural methods for proper slope mitigation. This study aims to determine the difference in stability behavior of Geogrid, Cantilever wall and Gravity wall as slope reinforcement using Plaxis 8.2 computer program. As the results of this study indicate that in stabiliy behavior of Geogrid as slope reinforcement figures 2.4 safety factor and has 8.15 mm total displacement as the lowest figures. On the structure of slope reinforcement using Cantilever Wall has 2.6 safety factor as the safest figures and also has 20.08mm total displacement as the highest figures. Meanwhile on the structure of slope reinforcement using Gravity wall has 2.4 safety factor, the same as Geogrid safety factor figures and has 19.17 mm total displacement figures, nearly the same as Cantilever wall total displacement figures. Thus the results of the study of several methods of slope reinforcement structures can be a recommendation in considering methods of proper slope mitigation in accordance with the characteristics of different problems on the fields.
