The trending use of Geotubes in Korea has initiated numerous researches and case studies that where performed mostly in field tests. However, there has been no research which analysis the behavior of the geotube deformation through a field size model which exclude external factors. This paper introduces a large scale experimental tank that uses a geotube with properties similar to that of field sizes. The large scale experimental tank will be used to examine the behavior of geotube and reclaimed soil’s interaction and deformation in order to improve the geotube construction technique.
