Özet
In the present study, the contribution of geogrid reinforcement on the stability of a sloped fill was investigated under two and three-dimensional conditions by Finite Element Method (FEM). Analyses were carried out to investigate and establish the relationship between the stability of the slope and the various geogrid parameters including the depth of the single layer of geogrid, number of geogrid layers, vertical spacing of geogrid layers, and length of geogrid layers. Also, the effect of two dimensional and three dimensional modeling on the FEM analyses results were evaluated. Results showed that reinforcement had increased significantly the stability of slope and the configuration of reinforcement in soil is crucial to ensure the reinforcement effect in reinforced slope design. It was also reached that the optimum reinforcement parameters are in close agreement for two and three-dimensional cases and slight differences were observed between the safety factors.
