This report presents the fundamental limit equilibrium slope stability equations required to compute the stability of earth slopes containing synthetic reinforcement "geogrids". The limit equilibrium equations were incorporated into a computer program, UTEXAS2, which was then used to perform a number of calculations for verification. Results of the calculations were compared with other published solutions and with the results of other limit equilibrium slope stability computations based on several simplified approximations. An important consideration in the design of reinforced slopes is the magnitude of the force which can be developed in the reinforcement. A series of finite element calculations were performed to estimate potential elongation strain in reinforcement. The finite element computations simulated the expansion of soil in a compacted earth slope and were used to estimate probable strain in reinforcement.
