A Study on Grid Effect and Applicability of Composite Reinforcement

In this study, laboratory pull-out tests and finite element modeling are carried out focused on the grid effects of geogrid and the analyses of friction characteristics associated with interaction behaviors of the composite reinforcement composed of geogrid with a superior function in tensile resistance and geotextile with sufficient drainage effects. In addition, drainage effects of the geotextile below geogrid are examined based on the analysis of finite difference numerical modeling. From the present investigation, it is concluded that the geosynthetic composite reinforcement in the weathered granite backfills may possibly be used to achieve effects on both a reduction of deformations and an increase of the tensile resistance, together with drainage effects due to the geotextile.
