People have paid attention to the use of supportive elements in retrofitting and soil improvement since a long time ego. Nowadays, the capability of reinforcement soil applications has been showed in different civil engineering projects. In order to increase of bearing soil capacity and reduce the settlement of structure, Geosynthetic Cellular System (GCS) has been invented. GCS consists of frame, geosynthetic fabric and soil. In this research, experimental and analytical behavior of small scale geosynthetic cellular systems has been analyzed. Our test case is a cylindrical specimen filled of sand from the beach of Khazar Sea. These cylinders are 10.5 cm in high and theirs base circle diameter are 10 cm in unreinforcement and reinforcement condition. Experimental studies were done with Teri axial test without back pressure and analytical studies were done with finite element soft ware (ABAQUS 6.7). Also in this research, the effect of vertical and horizontal reinforcement, the number of reinforcement, and their arrangement effect in the increase of bearing capacity, the decrease of settlement and lateral deformation of the instance have been presented. The experimental results and analytical studies are completely comparable and analytical results cover the experimental results. Also the results show that the reinforcement elements extremely cause to increase the bearing capacity and decrease settlement and lateral deformation. But, the horizontal reinforcement facilities in construct make it better than vertical reinforcement.
