Abstract:Geogrid plays an important role in geotechnical, transportation and water conservancy projects. Geogrid and soil are regarded as a kind of general composite material for which the representative cell is selected reasonably. A numerical model to evaluate equivalent elastic constitutive parameters is developed via a multi-scale asymptotic analysis for periodic structures-based homogenizing technology, and the effects of properties and sizes of component materials on the macro-equivalent elastic constitutive parameters can be taken into account conveniently. The work presented here may provide valuable reference for the further application of geogrid and help in the promotion of the forecast of the geogrid and soil macro-equivalent creep constitutive properties.
