Abstract: Geosynthetic-reinforced slopes are generally compacted fill embankments that incorporate geosynthetic layers as tensile reinforcement to enhance stability. The reinforcement holds together the soil mass from both sides of the failure surface, thus increasing the factor of safety of the existing slope. In the present study, the behavior of footing and settlements on reinforced and unreinforced slopes has been experimentally investigated. Model tests, (including that for unreinforced cases), were conducted by varying parameters such as the distance of footing from the edge of slope at crest, type of reinforcement and placing the reinforcement internally or externally. In the present study 2-layers of reinforcement placed internally and 1-layer of reinforcement placed externally on the slope face is used. The observed failure surface is plotted. The results were then analyzed to establish both qualitative and quantitative relationship between the bearing capacity, settlement and the reinforcement physical parameters. The results for the reinforced system placed either internally or externally (for either the settlement or ultimate capacity) that are normalized with respect to the corresponding results derived for the footing on unreinforced slopes has been presented. The results indicate that the increase in the bearing capacity of footing and decrease in the settlement on sloping ground can be significant by the inclusion of reinforcement layers in the slope either internally or externally. Modeling is also done by using Slope/W software package to predict the failure surface and factor of safety of the slope without reinforcement and with internal and external reinforcement. ii
