This paper presents the design chart to evaluate the two-demensional stability of geoteztilereinforcement embankments on soft foundations. The potential failure surface in this study is assumed as the logarithmic spiral curves refracted at the boundary of layers. To facilitate the iterative calculations, a program that determines the geoteztile tensile force for geotextilereinforcement embankments was developed. This program can be used for situations with a variety of soil layers and soil types. And it can be also used for a static or seismic condition. A series of calculations has been made for a schematised situation. The results of these computation are shown in design charts. Considering static or seismic load strate, these charts in the preliminary stage of the design provide a reasonable estimate of geoteztile tensile force for geotextile-reinforcement embankments on softs foundations. In the final swage a more detailed calculation can be made by developed programs.
