Research Abstract

This investigation aims at rationally explaining the mechanical behavior of the soil structure reinforced by geosynthetics. The attention is paid to confining effect by the geosynthetics under shearing. The confining effect is interpreted as the mechanical interaction such that the reinforcement material works so as to prevent dilative deformation of soils. The elasto-plastic constitutive models which can describe the dilative deformation of soils under shearing are introduced and applied to the finite element simulation of the mechanical behavior of soil structure reinforced by geosynthetics. A full-scale in-situ model test, which was carried out in Kanazawa is chosen to analyse. After verification of applicability of employed methodology to the analysis of the model test, the computed results are compared with the monitored behavior of the soil structure reinforced by geosynthetics in the model test.
