Recently, geotextile tube method can be widely applied to the river, costal and marine in the construction field, such as embankment,groin, breakwater, dyke structures and so on, in advanced countries of the world. And that has been constructed at the temporary roadfor incheon, ilsan-bridge construction and coast erosion protection in republic of korea. Geotextile tube is a tube shaped geotextileproduct and hydraulic pumping filled with dredged soils. In this paper, the numerical analysis was performed to investigate thebehavior of geotextile tube with various properties of material character, shape condition, construction pressure and so on. Also, thefield test was conducted in order to identify the construction ability of Samangum waterproof embankment using geotextile tube. According to the applied of field test, geotextile tube was 65 m long and 4.0 m diameter. Also, the permeability coefficient andultimate tensile strength of geotextile tube is 1.6×10－1 cm/sec and 205.26 kN/m, respectively. As a result of filed test, when filled,geotextile tube does not attain the same as its unfilled theoretical diameter, but may reach approximately of 55 percent of thetheoretical diameter. At the time, geotextile tubes were 12.56 m in circumference and filled to a height of about 2.2 m. This paperpresents case study on field application and behavior analysis of the saemangum waterproof embankment donggin 1 division constructionusing geotextile tube.
