2、ificant difference between assumed and measured values of the wall displacements and axial forces in geosynthetic reinforcements. This difference is caused by the conservative approach of conventional analytical methods and by the high values of the safety factors of geosynthetic reinforcements that

3、 undervalue their strength parameters. Therefore, deformation properties of the reinforcements and their interaction with soil environment become more important because strength parameters are not fully reached. Analysis of quantities, such as wall face displacements, axial forces and strains in the

4、 reinforcements using analytical methods and numerical modelling, is presented in this paper. Keywords: FEM; geosynthetics; internal stability; retaining wall; soil-reinforcement interaction; 1. Introduction Use of geosynthetic materials for reinforcing purposes allows us to replace the massive conc

5、rete retaining walls with reinforced earth structures that have advantages in realisation of the structure on soft soils. Reinforced earth structures also withstand the differential settlement very well. Design of these structures includes verification of global and internal stability. Global stabil

6、ity check is based on the gravity walls theory, with reinforced volume of the soil considered as a rigid block. Several methods of internal stability verification, which were calibrated by the monitoring of real structures, were developed. Beside the static equilibrium, these methods consider the influence of the reinforcement stiffness on overall structure stiffness, axial forces and strains of the reinforcement. Despite the improvements of these methods, outputs of the monitoring mention
