In spite of several theoretical models developed during four decades ago to predict the bearing capacity of foundation on geogrid reinforced soil, no unique theoretical model can best simulate the behavior for all cases of foundations on different reinforced soil where more verifications are required to confirm that. This paper includes the evaluation of several theoretical models that predict the bearing capacity of foundation on geogrid reinforced soil by comparing the results with the experimental results. Three types of foundation was used: strip, rectangular and square foundation. The research considered two types of soils: silty clay and sandy soil. Although the theoretical models used in this study gave a promised validation with an experimental results, it need more study to improve these models. Relatively, the best model is the model that was previously developed based on assuming punching in upper reinforced layers and then general shear failure on the other layers. A method of computing the tensile force induced in the reinforced layer based on the value of elastic settlement in silty clay was proposed instead of method based on a range of strain values which proposed in the literatures. The contribution of this study was that the evaluation of the available theoretical models with the experimental results may adopt a best theoretical models which may be used in design of a foundations on a reinforced local soils.
