Bearing capacity and failure mechanism of reinforced foundations based on rigid-plastic finite element formulation
A series of model loading tests on both unreinforced and reinforced foundations have been carried out, and in these tests the ground was modelled by aluminium rods. A rigid-plastic finite element analysis considering the effect of geometrical nonlinearity has been conducted to quantitatively investigate both the increase of calculated bearing capacity and the progress in deformation localization corresponding to the settlement of a loading plate. In the analysis, the reinforcing material and the surrounding soil were modelled as a composite material. Based on the comparative study between the test results and the numerical analysis, it is concluded that the proposed numerical method is capable of investigating quantitatively not only the bearing capacity but also the failure mechanism. In addition, the effectiveness of the proposed numerical analysis has been confirmed.
