Abstract
A pullout test model is proposed using hyperbolic relation for highly extensible soil-reinforcement. The non-linear equation for interface pullout mechanism was non-dimensionalised, expressed in finite difference form and solved numerically using the Guass-Siedel technique. A parametric study was carried out for various ranges of relative stiffness and relative bond resistance. The normalised load-displacement relations and the variations of pullout force and reinforcement displacements with distance, are presented. The interface pullout response of the model is compared with the available experimental pullout test results for geotextile, polymer and nylon geosynthetic reinforcements.
