Excavation nearby the existing structures is being performed vigorously to get the greatest use of land along with fast economic growth in the downtown area. The application of soil nailing system gradually increases because of an advantage of soil nailing system adjacently constructed in the existing structures. Geosynthetic fiber soil nailing system developed in this study can prevent ground environment pollution by re-bar corrosion because it is strengthened by environment favorable geosynthetic fiber instead of re-bar. Geosynthetic fiber soil nailing system can be expected to reduce construction cost because it is ease to remove soil nail structure (fiber strip+ PE. pipe+cement grout structure) constructed in past and minimize waste of resource because it is a new concept of geosynthetic fiber using waste PET. In this study, friction resistance by pull-out is considered as main resistance except resistance formed by flexural rigidity of nail observing that resistance of flexural rigidity is about 0~15 % of whole safety factor according to degree of flexural rigidity in general soil nail wall(Jones, 1990) and application of geosynthetic fiber soil nailing system is evaluated through laboratory tensile strength test. Hereafter, it will be made a comparative study of long·short term pull-out strain characteristics in comparison with the general soil nailing system by performing of a field pull-out test and evaluated pull-out behavior characteristics of geosynthetic fiber soil nailing system.
