Geocells are one types of geosynthetics that have been recently used for soil reinforcement. Because of the unique performance of this type of reinforcement system (high confinement due to the three-dimensional geometry), their application is developing, and extensive studies are being carried out on these systems. Many laboratory studies have been conducted on geocell reinforcement systems, while few studies have been done on numerical analysis of their performance which is necessary for understanding their exact behavior. As a result, theoretical methods and the current design of these systems are less developed than their applications in various fields including road construction. Therefore, the present research aimed to study the performance of geocell reinforcement system in road embankments and the factors affecting it based on the numerical method of finite difference using a real more accurate approach. In addition, the effect of parameters of geocell infilled soil on the performance of these embankments were studied.
