| description | To understand the improved behaviour of the Isometric Cogged Biaxial Grid (ICBG), this research is devoted to evaluating the factors affecting the soil-grid interaction by separating the effect of friction, shear, and passive resistance between the soil and grid. Laboratory pull-out tests are carried out using two types of soil (sand and crushed limestone) reinforced by three different types of reinforcements, which are; a Solid Plate, a Biaxial Grid and the ICBG. It is found that the ICBG, which is a biaxial grid modified by distributing cogs on both sides of its ribs, added a new factor to the resistance mechanism, which is the interlock with soil aggregates. This factor shares about 34% of the resistance value. Moreover, the design of the ICBG gives much more benefit to the passive resistance and introduces interlocking between the ribs and the aggregates which raises the final passive resistance by about 50% over the traditional Biaxial Grid. It is also found that for the ICBG each of the passive force and the shear force share about 47% of the resisting mechanism, while in the case of using the Biaxial Grid the shear force has the demonstrative role with a percentage of more than 70%. |
