Abstract
The article presents a study on the numerical modeling of polymer rigid geogrids in the Plaxis 2D software package, aimed at evaluating their influence on the stability and deformation characteristics of reinforced soil structures. The methodology for determining the key parameters of geogrids, such as short-term and long-term strength, axial stiffness, and deformation properties under expected loads, is considered. The study analyzes the effects of temperature conditions, material service life, and operating conditions on the strength and deformation behavior of Tensar RE geogrids. Particular attention is given to the configuration of contact zones between the geogrid and soil, which allows accounting for friction and adhesion, ensuring a realistic representation of the interaction mechanics between materials in reinforced soils. The use of both elastic and elastoplastic models enables a more accurate assessment of the behavior of reinforced soil systems under various types of loads. The conducted analysis allows predicting stress and displacement distributions within the structure, evaluating reinforcement effectiveness, and identifying critical areas for engineering design. The results demonstrate that numerical modeling in Plaxis 2D is a powerful tool for optimizing the design of engineered structures with reinforced soils, ensuring their durability and minimizing the risk of deformations. The developed methodology allows engineers to make informed decisions when selecting geogrids, configuring structural parameters, and predicting the behavior of the soil–geogrid system under real operating conditions
