BEHAVIOURAL STUDY OF A REINFORCED ANALOGICAL SOIL UNDER EXTERNAL LOADS

This paper sets out to explore the changes in stress distribution for a medium reinforced by flexible geomembrane layers. The experimental results are compared to the theoretical results obtained using the Boussinesq method, and numerical results obtained using the Fast Lagrangian Analysis of Continua calculation program, (FLAC). The tests carried out on Schneebeli's analogical medium, which consists of a stack of small steel rollers, showed that, even in the case of loaded, non-reinforced soils, stress distribution follows Boussinesq's law, especially for high loads and despite the discrete nature of the experimental medium being used. In the case of loaded reinforced soil, the presence of reinforcing layers has no bearing on the vertical stress, while the horizontal stress shows a large increase.
