To improve the modeling of friction between the ground and reinforcing inclusions, such as steel strips in reinforced earth walls, a specific type of finite element was introduced in the CESAR-LCPC finite element code. Simulations were carried out, in which these elements were used in combination with a linear elastic-perfectly plastic model to describe the interaction between the ground and the inclusions. With this simple interaction model, however, it was not possible to reproduce the observed behavior of a full-scale, experimental wall or the results of pull-out tests carried out on the same wall under the same set of parameters. Therefore, two more complex models were introduced for the soil–inclusion interaction, which led to a much better agreement between the numerical results and the experimental observations.
