Abstract

The research was conducted in the West Ring Road of Sadawarna Dam, Subang Regency. This research aims to provide recommendations for the design of cantilever retaining wall to increase the value of the slope safety factor in the research area. Calculation of the value of the slope safety factor uses the limit equilibrium method with the Janbu calculation method. In actual conditions, the value of the slope safety factor shows an unstable value referring to SNI 8460:2017, namely in static conditions with a vehicle load is 1.31 and in pseudostatic conditions with a vehicle load is 1.083. Slope strengthening was carried out using cantilever retaining wall. The retaining wall design that has been made meets the criteria for stability against overturning, stability against sliding, and stability for the bearing capacity of the soil. The safety factor value for slope with retaining wall shows a stable FS value referring to SNI 8460:2017, namely 1.53 in static conditions with vehicle loads and 1.11 in pseudostatic conditions with vehicle loads. Keyword: slope, safety factor, retaining wall, cantilever

Abstract

Infrastructure development is a common thing that happened in Indonesia, especially house construction that happened in Cipatat, West Bandung, West Java. One of the important things in construction is a foundation and one of the foundation’s types is a shallow foundation. Soil bearing capacity is one of several things that used to calculate foundation planning. This research is using the Terzaghi method for soil bearing capacity. The data was obtained by taking the disturbed sample from three different locations. Those samples were tested in a laboratory, the test is a direct shear test to know about soil bearing capacity's value. The result is soil bearing capacity value range between 5.47 ton/m2 - 26.52 ton/m2. That value for soil bearing capacity is categorized as low.
