Numerical investigations of interaction between geogrid/wire fabric reinforcement and cohesionless fill in pull-out test

Abstract

The interaction between geogrid/wire fabric reinforcement and fill material in reinforced earth walls, as well as its quantification, is a complex problem that depends on a number of factors. This paper presents and discusses state of the art related to numerical simulations of pull-out tests used for investigation of interaction between cohesionless fill and reinforcement. In addition, the results of a specially designed group of numerical simulations are presented and compared with recommendations of American and European standards related to such experiments.
