In this thesis finite element analyses were performed to investigate the behavior of fill fences installed in underground mines to retain Cemented Paste Backfill (CPB) pressure. For this purpose, two fill fences installed and tested in the Cayeli mine in Turkey were modeled using a 2-D nonlinear finite element analysis program, Augustus-2, and a 3-D nonlinear finite element analysis program VecTor4, and the results were compared with measured field data. Different models were employed representing the material properties, boundary conditions, reinforcement ratio, and geometric properties, and it was found that boundary conditions (stiffness of surrounding rocks) has the highest influence on the pressure capacity of the fence among the other factors. The accuracy of the Augustus-2 program was investigated by modeling and comparing the analytical response with test results of 12 axially restrained beams tested by Su et al. (2009).
