This paper presents a finite difference iteration procedure for solving the two differential equations of a geosynthetic reinforced foundation model. This paper focuses on (a) loading transfer from loading surface to the soft soil and (b) the influence of model parameters on the settlement and the mobilized tension force in the geosynthetics. The reason why geosynthetic reinforced granular fills over soft soil can reduce settlement and increase bearing capacity is that the load transferred to the soft soil is reduced. The most effective measure for reducing foundation settlement is to increase the stiffness of the granular fills.
