This paper presents the deterministic model to evaluate the two dimensional stability of geotextile-reinforced embankments on soft foundations. The potential failure surfaces in this study are assumed as the logarithmic spiral curves refracted at the boundary of layers. To facilitate the iterative calculations, we developed a program that determines the geotextile tensile force for an geoteztile-reinforced embankments. This program can be used for situations with a varying number of soil layers and soil types. A series of calculations have been made for a schematised situation. The results of these series are collected in stability charts, which are compared with those by circular potential failure surfaces. Using these charts in an early stage of the design provides a reasonable estimate of the stability of geotextile-reinforced embankments. In a later stage a more detailed calculation can be made by the developed programs.
