Accurate modelling of granular particles’ effects plays a crucial role when analyzing the behavior of soils reinforced with geogrids. In addition to the field and laboratory tests, computer simulations help understanding influences of geogrid interlock actions in the overall behavior. In this study, we present the results of our first attempt for simulating ballast particles together with geogrid reinforcements using our own simulation tool. For this purpose, a simulation game software is written with a graphical user interface, that will allow the user to interact with the soil – geogrid medium. With the introduction of geogrid type and ballast gradation information, the software can generate a model that shows how ballast fills the voids of the geogrid. The model is developed based on both physical and mathematical constraints. Various geogrid types produced by different companies are embedded in the software. A powerful feature of the software is that custom geogrid types can be generated by the user through the interacting with the geotechnical designer. In addition, the software can analyze various gradation curves and their proper models very fast. The results may influence the design of new geogrids to produce more effective improvement solutions.
