Abstract

The methods currently used for the design of reinforced earth walls with quasi‐inextensible metallic reinforcements are essentially based either upon the limit stress analysis concept or empirical relationships derived from observations on full scale structures. The development of an adequate working stress design method for these structures requires a fundamental understanding of the reinforcement effect on the load‐deformation behavior of the soil and a rational, yet relatively simple, load transfer model to simulate the soil‐reinforcement interaction. Furthermore, the response of the composite‐reinforced soil material to loading is highly dependent upon the initial state of stress and strain in the soil, and therefore the construction process and soil compaction can significantly affect the structure behavior under the expected working loads. A strain compatibility design approach which is fundamentally based on the analogy between the plane strain shear mechanism which develops along a potential failu...
