STARES (STability Analysis of REinforced Soil) for Windows is a computer program which enables the user to compute the stability of an earth mass stabilised by reinforcement using an analysis based on Bishop's (1955) simplified method for unreinforced slopes. In these analyses the stabilisation provided by the reinforcement is assumed to be entirely due to the axial force generated along the reinforcement. Thus, the contribution that the shear forces in the reinforcement make towards improving the factor of safety against failure are assumed to be negligible and therefore not included in the analysis. This assumption means that STARES is suitable for assessing the internal stability of the following types of problems:
wall systems retaining soil stabilised by the inclusion of metallic (e.g. Reinforced Earth) or non-metallic (e.g. Freyssisol by Austress Freyssinet) strips,
slopes and walls stabilised with soil nails,
slopes and walls stabilised with geotextiles or geomembranes.
