다단식 지오텍스타일 튜브구조물의 시공시 거동계측

Domestic geotextile tube dike was started by Younjin bay for protection beach line with an geotextile tube of 3m diameter and 50m length filled with sand. After that geotextile tube was constructed in front of Uljin hydro and nuclear corporation for the protection of environment around that. Recently, it has been using as protecting for seashore or temporary structure such as Ilsan bridge construction site constructed with 7㎞ length and with second layer structure. A behavior of site in geotechnical engineering has been known by according to development of basic theory concerned with geotechnical engineering and due to in situ testing, laboratory testing, design and construction. But real behavior of soil site can be different because of non homogeneity of site, limitation of investigation or testing for construction, and simplify of a model that is a structure for analysis and condition of a construction. Therefore, a device of monitoring for precision result need to achieve an effective effort or safety. In this research it will be analyzed as a physical monitoring behavior of stacked geotextile tube dike on construction in Incheon bridge for the first time with using analysis for safety and monitoring of temporary structure on construction.
