摘要

The paper presents the results of the numerical analyses carried out with the well-known FE code PLAXIS to simulate the response of a lg small-scale model wall reinforced with polypropylene geogrids, under loads applied on top of the sand bed behind the wall. The capability and reliability of the numerical code to describe the measured behaviour is discussed, particularly with reference to the most suitable material model and parameters. A good general agreement between experimental data and numerical results is shown, especially when considering the complexity of the physical system, characterized by an initially low stress level combined with a highly confined soil-geogrids-wall interaction.
