One of the common features used for improving the bearing capacity of footings adjacent to a soil slope is reinforcement by geosynthetics. These elements may somehow isolate the soil inside of the geosynthetic and eliminate shear-stress mobilization. In this study, a new kind of three-dimensional geosynthetics called expandable braided sleeve (braid) and geogrid have used a laboratory modeling approach to investigate the effects of different variables on the bearing capacity of footings on soil slopes. Some parameters, including relative density and soil compaction, were assumed constant in all tests. In contrast, other variable parameters, including the vertical distance between the surface and the first layer of geosynthetics, the distance of a footing from the slope edge, and planar and tabular shapes of braid and geogrid were investigated. Results demonstrated that for the same conditions of some parameters, cylindrical reinforcement has a more significant effect than the planar form of the reinforcement concerning enhancing bearing capacity and settlement reduction. Inclusion of geosynthetic reinforcement can also reduce stress concentration and distribute the applied load, resulting in settlement reduction. Moreover, braid material was found to result in somehow better performance than geogrids in reducing settlement.
