Abstract

Soil nailing is an in-situ reinforcement technique to retain excavations constructed by successive increments. A 3-D FEM code is developed for simulation of this complex system by incorporating isoparametric elements to model soil, nail and their interface. Both material and geometrical nonlinearities are considered in the simulation. The developed code uses HISS plasticity model for soil and assumes elastic deformation of nails during soil-nail interaction. Soil to nail interface is modelled by using thin interface elements, which obey elastic-perfectly plastic behavior. The code is used to model actual field construction of soil-nailed walls for better understanding of their behavior during and after construction. In the analysis of typical soil-nailed walls, results presented consist of deformation, stress and nail force distributions.
