ABSTRACT
Finite elements models (FEM) programs have become an integral part of geotechnical analysis. However, the inclusion of geosynthetics in the model often gives results that differ from the actual behavior of the structure. The classic way is the modeling of a geogrid in the form of a membrane with specified strength parameters. The list of these parameters and methods for their determination are not spelled out clearly enough in the design and test standards. The author proposes to investigate both the finite element and analytical models and estimate their cohesion with the monitoring results and ability to fully consider the effect of geogrids.
