STRAIN COMPATIBILITY ANALYSIS FOR GEOSYNTHETICS REINFORCED SOIL WALLS

A method is presented that addresses the need for the development of strain compatibility design approaches capable of predicting the tension forces that would be generated in the geosynthetic reinforcements under the expected working loads. The method allows for the evaluation of the effect of soil dilatancy and extensibility of the reinforcement on the generated tension forces and structure stability. Two design procedures are presented: the first considers an elastoplastic strain hardening soil model and uses the finite difference technique to incrementally simulate the construction process; the second is based on a closed form analytical solution assuming the soil to be a Mohr-Coulomb-type rigid plastic material with a nonassociated flow rule. These two soil models are taken into consideration in order to evaluate the probable constuction effect on the mobilized tension forces. Study findings are discussed.
