Numerical Simulation of Pullout Tests in Residual Clayey Silt
This paper will present a comparison between results of field pullout tests and numerical simulations. The constitutive models and parameters used will be discussed. An earth dike was constructed in Poços de Caldas, Brazil, to contain 1,500,000 cubic meters of Bauxite residues. A geogrid-reinforced wall was built on the dike's top to reduce its width. PVA geogrids and local residual clayey silt were used. In order to verify the pullout behavior of the geogrid-soil system 16 large-scale pullout tests were conducted in an experimental fill. Pullout tests were simulated by finite element method. Hyperbolic elastoplastic model was used for the soil and linear elastic model was used for the geogrid. Soil parameters were determined by triaxial tests on undisturbed samples retrieved from the fill. An equivalent static distributed load was used to simulate compaction. Simulation results compare well to measured behavior.
