Abstract

The pullout test was effective in order to study the interaction behavior between soil and geogrid in the reinforced zone. Therefore its resulting properties had important implications on the reinforced soil structure practice. It had been demonstrated by experimental studies that several parameters (geotechnical properties of soil, geogrid properties, applied vertical effective stress) influenced on the pullout behavior and pullout resistance. As a micro-mechanics study is difficult to carry out in traditional study, a discrete element modelling of pullout test was employed here to investigate the pullout behavior of geogrid embedded in a compacted granular soil. The discrete element modelling was used to investigate the interaction between the geogrid and compacted granular soil paying attention to the properties of geogrid, taking into account the compaction effect linked with porosity. Compared with the experimental results, the discrete modelling was favourable. The discrete element modelling was capable of evaluating the interaction between soil and reinforcement.
