... with geocomposite layers was found to be superior to the geogrid reinforced soil walls with the chimney drain. Figure 3. Tensile load-strain behaviour of geosynthetic materials  Figure 4. Details of facing panels (all dimensions in mm) Centrifuge model tests were performed using a 4.5 m...

... similitude conditions between a model and prototype can be achieved by increasing the gravity level in the model through the application of centrifugal forces. Relevant prototype geometric and constitutive parameters can be scaled for centrifuge models according to scaling laws summarized by Ko (1988...

... and the type of backfill soil as constant. Finally, stability analysis of the centrifuge models was carried out to corroborate observed failure mechanisms. A major difficulty encountered in model studies involving geosynthetic materials is selection, modelling and instrumentation of idealised materials...
