Abstract
Most of geosynthetic are usually employed as a thin sheet-like membrane and reinforce an embankment structure or a poor ground. A geocell mattress, which is one of the reinforced earth construction methods, is assembled in a three dimensional slab structure such as a honeycomb and filled with soil materials. This can improve the mechanical properties of soil structure. The geocell can confine the deformation of soil particles in each cell and a result the geocell slab has a high bending rigidity and shows high stress distribution effects and a restriction of flow deformation of foundation soils.
In this study laboratory model tests are carried out using a two layer system composing a geocell slab placed on a EPS resilient subbase layer. An elastic analysis of the layer under a circular load are made. Experimental and theoretical results are compared and discussed.
